A tennis ball bounces on the floor three times. If each time it loses 11% of its energy due to heating, how high does it rise af
aalyn [17]

Answer:

h = 3.10 m

Explanation:

As we know that after each bounce it will lose its 11% of energy

So remaining energy after each bounce is 89%

so let say its initial energy is E

so after first bounce the energy is

E_1 = 0.89 E

after 2nd bounce the energy is

E_2 = 0.89(0.89 E)

After third bounce the energy is

E_3 = (0.89)(0.89)(0.89)E

here initial energy is given as

E = mgH_o

now let say final height is "h" so after third bounce the energy is given as

E_3 = mgh

now from above equation we have

mgh = (0.89)(0.89)(0.89)(mgH)

h = 0.705H

h = 0.705(4.4 m)

h = 3.10 m

A laser pulse takes 2.56 seconds to travel from Earth to the Moon and return. Use this to calculate how far away the Moon is. Ho
Deffense [45]

Answer:

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

Explanation:

The laser pulse has an ondulatory nature as electromagnetic wave, which can travel in the void. Speed of light is constant and distance between Earth and the Moon is:

x = 0.5\cdot c\cdot \Delta t

x = 0.5\cdot (3\times 10^{5}\,\frac{km}{s})\cdot (2.56\,s)

x = 3.84\times 10^{5}\,km

This delay affect conversations in the sense that recipient will be receive the message just 2.56 seconds after the message was sent.

A 3 kg object is moving along a horizontal surface. The kinetic energy of the object is increasing at a constant rate of 6 J/m;
Whitepunk [10]

To solve this problem we will apply the concepts of energy conservation and Newton's second law that defines force as the product of the object's mass with its acceleration. Additionally we will apply concepts related to the kinematics equations of linear motion.

For conservation of energy we have that work is equal to kinetic energy therefore,

W = KE

Fd = \frac{1}{2} mv^2

Here,

F = Force

d = Displacement

m = Mass

v= Velocity

At the same time we have the relation of

F = \frac{W}{d}

Therefore the value of the force can be interpreted as the rate of increase in energy per unit of distance, which makes it equivalent to

F = \frac{W}{d} = 6J/m

Applying Newton's Second Law

F = ma

6J/m = (3kg)a

a = 2m/s^2

In 4 seconds final velocity of the object becomes

v = at

v= 2*4

v= 8m/s

Then the work done is equal to,

W = KE

W = \frac{1}{2} mv^2

W = \frac{1}{2} (3)(82)

W = 96J

Then the displacement is,

W = F*d

d = \frac{W}{F}

d = \frac{96}{6}

d = 16 m

Therefore the distance moved is 16m
