Answer:

2.12m/s

Explanation:

Given parameters:

Force on trolley  = 1.5N

Mass of trolley  = 0.2kg

Unknown:

Velocity of the trolley  = ?

Solution:

To solve this problem, we first find the acceleration of the trolley;

          Force  = mass x acceleration

         Acceleration  = [tex]\frac{Force }{mass}[/tex]

Insert the parameters and solve;

          Acceleration  = [tex]\frac{1.5}{0.2}[/tex]   = 7.5m/s²

Now to find the acceleration;

  Initial velocity  = 0m/s

  v² = u² + 2aS

v is the final velocity

u is the initial velocity

a is the acceleration

S is the distance

  Distance  = 30cm and this is 0.3m

     v² = 0² + 2(7.5)0.3  = 4.5

     v = √4.5 = 2.12m/s

Answer:

The answer is:

VA= 33 m/S

VB= 27.8 m/s

VC= 50 m/s

VD=66.7 m/s

VE=35.7 m/s

So, the Legs from the highest velocity to the lower are:

D - C - E - A - B

The explanation:

we are going to use the velocity formula:

Velocity = distance (m) / time (s)

So,

A) when D = 18 Km = 18000 m

and t = 9 min = 9*60 =540 s

So V = 18000m/ 540 S

      = 33 m/S

B) when D = 25 Km = 25000 m

and t = 15 min = 15 * 60 = 900 S

So V = 25000m / 900S

     = 27.8 m/s

C) when D = 24 Km = 24000 m

and t = 8 min = 8 * 60 = 480 s

So V = 24000m / 480s

     = 50 m/s

D) when D = 48 Km = 48000 m

and t = 12 min = 12 * 60 = 720 s

So V = 48000 m / 720s

       =66.7 m/s

E) when D = 15 km = 15000m

and t = 7 min = 7 * 60 = 420 s

So V = 15000m / 420s

      = 35.7 m/s

Answer:

The generated sound wave will not be able to reflect off of the object.

Explanation:

The statement that best describes this situation is: The generated sound wave will not be able to reflect off of the object.

An ultrasound machine is a device that is used to capture images in the human body for review by a medical examiner. The machine gives off sound waves that are reflected off body structures.

So, for the ultrasound machine being described, the absence of kidney stones will cause a non-reflection of the object to be captured.

Since the machine is in good working condition, the sound wave will be generated.

Final Velocity = 14m/s

Displacement = 56m

Explanation:

U (initial velocity) = 2m/s

A (acceleration) = 3m/s^2

T (time) = 4s

v (final velocity) = ?

S (displacement) = ?

FIRST FIND FINAL VELOCITY:

[tex]a = \frac{v - u}{t} [/tex]

(i) Multiply both sides by t:

[tex]a \times t = v - u[/tex]

(ii) Add u to both sides:

[tex](a \times t) + u = v[/tex]

(iii) rearrange formula:

[tex]v = (a \times t) + u[/tex]

v = ( 3 × 4 ) + 2

v = 12 + 2

v = 14m/s

SECOND FIND DISPLACEMENT:

[tex]v = \frac{s}{t} [/tex]

(i) Multiply both sides by t:

[tex]v \times t = s[/tex]

(ii) Rearrange formula:

[tex]s = v \times t[/tex]

s = 14 × 4

s = 56m

Answer:

Yea its A

Explanation:

Answer:

A.) 5s

B.) 2.29s

C.) 39.6 m/s

Explanation:

Given that a kid throws a rock off the edge of a cliff 60.0 m high. When he drops the rock, it takes 5,0sec for it to reach the ground below.

a.) Determine the time it takes to reach the ground below,

The time is 5s

b.) How long would it take the rock to hit the ground if he threw it down with a speed of 15m/sec?

Using the second equation of motion:

H = Ut + 1/2gt^2

Substitute all the parameters into the formula

60 = 15t + 1/2 × 9.8 × t^2

60 = 15t + 4.9t^2

Multiply all by 10

49t^2 + 150t - 600

t^2 + 3.06t = 12.24

( t + 1.53)^2 = 12.24 + 2.3409

t + 1.53 = sqrt ( 14.5809)

t = 3.82 - 1.53

t = 2.29s

is hit stmight upward and reach a maximum height of 80.0 m.

Using the third equation of motion

V^2 = U^2 - 2gH

At maximum height, V = 0

0 = U^2 - 2 × 9.8 × 80

U^2 = 1568

U = sqrt ( 1568)

U = 39.6 m/s

Answer:

Final velocity, V = 2.1213 m/s.

Explanation:

Given the following data;

Force, F = 1.50N

Mass, m = 0.2kg

Displacement, S = 30cm to meters = 30/100 = 0.3m

To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is given by the formula;

[tex] F = ma[/tex] .......equation 1

Where;

Making acceleration (a) the subject, we have;

[tex]Acceleration (a) = \frac{F}{m}[/tex]

Substituting into the above equation, we have;

[tex]Acceleration, a = \frac{1.5}{0.2}[/tex]

Acceleration, a = 7.5m/s²

Now to find the final velocity, we would use the third equation of motion;

[tex] V^{2} = U^{2} + 2aS [/tex] .....equation 2

Where;

Note: Since the trolley is starting from rest, we know that it's initial velocity is 0.

Substituting the values into equation 2, we have;

[tex] V^{2} = 0^{2} + 2*7.5*0.3[/tex]

[tex] V^{2} = 0 + 4.5[/tex]

[tex] V^{2} = 4.5[/tex]

Taking the square root, we have;

[tex] V = \sqrt {4.5}[/tex]

V = 2.1213 m/s.

Therefore, the speed of the trolley after accelerating from rest through 0.3 m, if friction is negligible is 2.1213 m/s.

Answer:

The end of the ramp is 38.416 m high

Explanation:

Horizontal Motion

When an object is thrown horizontally with an initial speed v and from a height h, it follows a curved path ruled by gravity.

The maximum horizontal distance traveled by the object can be calculated as follows:

[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]

If the maximum horizontal distance is known, we can solve the above equation for h:

[tex]\displaystyle h=\frac {d^2g}{2v^2}[/tex]

The skier initiates the horizontal motion at v=25 m/s and lands at a distance d=70 m from the base of the ramp. The height is now calculated:

[tex]\displaystyle h=\frac {70^2\cdot 9.8}{2\cdot 25^2}[/tex]

[tex]\displaystyle h=\frac {4900\cdot 9.8}{2\cdot 625}[/tex]

h= 38.416 m

The end of the ramp is 38.416 m high

Answer:

3. lost electrons.

Explanation:

An atom that has lost an electron is positively charged because the number of protons is now greater than the number of electrons in the atom.

If the number of protons and electrons are the same, the atom has no charge

If the protons > electrons, the atom becomes positively charged

If electrons > protons, the atom becomes negatively charged.

Atoms becomes charged by losing or gaining electrons.

Answer:

Explanation:

19000000000/ 1/3 = 57000000000

Answer:

The elements in the reactants are the same as the elements in the products

Explanation:

The condition for a balanced equation is as follows :

The number of atoms for each element in reactant = Number of atoms for each element in product.

Total charge on reactant and product must be same.

The example of a balanced equation is:

Reaction of carbon and hydrogen :

[tex]C+2H_2\rightarrow CH_4[/tex]

No. of carbon atom on Carbon on LHS = 1

No. of carbon atom on Hydrogen on LHS = 4

No. of carbon atom on Carbon on RHS = 1

No. of carbon atom on Hydrogen on RHS = 4

So, for a balanced equation, The elements in the reactants are the same as the elements in the products. Hence, the correct option (a).
