Answer:Kinetic energy of the girl and her bike is 5.544 kJ

Explanation:

Given that a girl is riding bike at speed of 12m/s

Also, mass of Girl is 55kg and mass of bike is 22kg

Let, Total mass of girl and bike be M=22+55=77kg

Now, Kinetic energy is given by K=

Hence, Kinetic energy of the girl and her bike will be

K=

K=

K=5544J

Thus, Kinetic energy of the girl and her bike is 5.544 kJ

Answer:

When we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.

Explanation:

As we know that Acceleration is the rate of change of velocity with respect to time, in terms of both speed and direction.

i.e.

a = Δv/Δt

so when we say that an object moving in the +x axis experiences an acceleration of 2.0 m/sec2, it really means the object is increasing its velocity by 2.0 m/s in every second.

Answer:

74.28 m/s

Explanation:

In this case, it is a zero launch angle in that the object is launched horizontally at a height H.

The formula to apply is:

[tex]R=v_o*\sqrt{\frac{2H}{g} }[/tex]

where

R= range, 450 m

H= height of building ,180 m

g= 9.81

vo= ? initial velocity

Applying the values to the equation;

[tex]450 = v_o*\sqrt{\frac{2*180}{9.81} } \\\\450=v_o*\sqrt{36.70} \\\\450=v_o*6.06\\\\450/6.06 = v_o\\\\74.28 m/s=v_o[/tex]

Answer:

A balloon is floating up into the air at 1 m/s.

Explanation:

Velocity is the displacement divided by the time;

   Velocity = [tex]\frac{displacement}{time}[/tex]

It is a vector quantity that has magnitude and direction.

The choice that shows a change in direction is a correct specification of velocity.

A balloon floating up into the air at 1m/s shows no directional change.

Answer: I personally recommend less screen time. As the Hollidays are approching, maybe spend time hanging decorations or going on hikes.

Answer:

1. Ask her if there's anything going on in her life that she would like to talk to you about.

2. Make sure she drinks lots of water and eats the right amount of food. Not treating your body right will mostly make you feel stressed.

3. Make sure she's staying active. Staying indoors, watching TV 24/7 with the doors closed, and over-eating is very unhealthy. Germs can also build-up and cause infections which would lead you to feel uneasy.

4. And most importantly, make sure she's not in a rocky relationship.

Answer:

'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Explanation:

As we know the independent variable is basically the variable the independent variable is the variable the researcher or a lab person tends to change or control, and its tendency to have a direct effect on the dependent variable.

In this example, two cars are on a track and accelerate to 60 mph. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured.

It means the 'covering' distance depends upon where the cars tend to stop. It can be a long-distance depending upon how fat the cars go before both cars slam on the brakes.

Therefore, 'distance' is a 'dependent' variable, and 'stopping' distance is 'an independent' variable.

Answer:

(I UNDERLINED AND MADE ITALIC THE MOST IMPORTANT INFORMATION) A vocation is an occupation to which a person is especially drawn or for which they are suited, trained, or qualified. Though now often used in non-Latin vocātiō 'a call, summons')religious contexts, the meanings of the term originated in Christianity.  (from

Explanation:

A call, summons, or impulsion to perform a certain function or enter a certain career, esp. a religious one. Vocation is defined as a call to do something, especially regarding religious work. The woman's desire to become a nun is an example of vocation. a strong impulse or inclination to follow a particular activity or career. a divine call to God's service or to the Christian life. a function or station in life to which one is called by God: the religious vocation; the vocation of marriage. There are many different types of vocations in today's society. The three significant vocations are, single life, married life, and religious life. Single life is one of the three types of vocation. Definition of Vocation and Career: Vocation is what you strive to do in your life. It is the career you want to be in. Career, on the other hand, is a series of jobs, even change of professions, in a lifetime of an individual. Vocation is literally your "calling", what you are good for or destined for. It usually is a property/talent/predisposition of your person. A mission, in contrast, is a particular task given to you. Even if you are on "a mission from God", there may be retirement from it eventually.

Answer:

The net force is 20N in the direction of the 80N force.

Explanation:

The net force is the resultant force acting on a body. This force is that singular force that will have the same magnitude and effect as the network of forces on a body.

 In this problem:

      Force 1 = 80N

      Force 2 = 60N

Net force  = Force 1  - Force 2

Net force  = 80N - 60N

Net force  = 20N

The net force is 20N in the direction of the 80N force.

Answer:

202.8m

Explanation:

Given that A pirate fires his cannon parallel to the water but 3.5 m above the water. The cannonball leaves the cannon with a velocity of 120 m/s. He misses his target and the cannonball splashes into the briny deep.

First calculate the total time travelled by using the second equation of motion

h = Ut + 1/2gt^2

Let assume that u = 0

And h = 3.5

Substitute all the parameters into the formula

3.5 = 1/2 × 9.8 × t^2

3.5 = 4.9t^2

t^2 = 3.5/4.9

t^2 = 0.7

t = 0.845s

To know how far the cannonball travel, let's use the equation

S = UT + 1/2at^2

But acceleration a = 0

T = 2t

T = 1.69s

S = 120 × 1.69

S = 202.834 m

Therefore, the distance travelled by the cannon ball is approximately 202.8m.

Answer:

bicycle A has a greater K.E.

Explanation:

K.E = 1/2mv²

bicycle A = 1/2 × 40 × 4² = 320J

bicycle B = 1/2 × 20 × 2² = 100J

bicycle A has a greater K.E. because it has bigger mass and moves with faster velocity

Answer:

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 2 × 5

We have the final answer as

Hope this helps plz hit the crown :D

Answer: (6.2 x 10^18m) (4.7 x 10^-10m)

multiply the decimal numbers first:  6.2 x 4.7 = 29.14

multiply the base ten numbers by adding the exponents:

10^18m x 10^-10m = 10^8m

now you have:

29.14 x 10^8m

that's it -- unless you need to write the final answer in scientific notation.  If so, you have to adjust the exponent for the base 10 to get:

2.914 x 10^(8m+1)
