Hi!

So if you drop a basketball from a higher height, it has more time to gather more energy, which it then forces against the ground and causes the ball to bounce.

Hope this helps! Sorry I didn't really use any technical terms!

The basketball do not bounce back to the same height after each drop due to the fact of loss of kinetic energy.

<u>Explanation: </u>

When the basketball or any ball is dropped off from a certain height it falls down under the influence of gravity with the kinetic energy which has been transferred to the ball with hand by dribble.

When the basketball hits the ground with the kinetic energy, it loses some of the energy to the ground and then with the action reaction pair with the ground, is bounced back but with lower energy to a lower height.

To solve this problem it is necessary to apply the concepts related to the conservation of the Gravitational Force and the centripetal force by equilibrium,

$F_g = F_c$

$\frac{GmM}{r^2} = \frac{mv^2}{r}$

Where,

m = Mass of spacecraft

M = Mass of Earth

r = Radius (Orbit)

G = Gravitational Universal Music

v = Velocity

Re-arrange to find the velocity

$\frac{GM}{r^2} = \frac{v^2}{r}$

$\frac{GM}{r} = v^2$

$v = \sqrt{\frac{GM}{r}}$

PART A ) The radius of the spacecraft's orbit is 2 times the radius of the earth, that is, considering the center of the earth, the spacecraft is 3 times at that distance. Replacing then,

$v = \sqrt{\frac{(6.67*10^{-11})(5.97*10^{24})}{3*(6.371*10^6)}}$
