**1.**What forces and impulse impact on a bouncing basketball?

I understand that it is the gravitational force, when it falls, then the normal force when it is on the way back. Are there any additional powers?

The momentum, I came to the potential energy = kinetic energy, where I got the speed. The impulse I got through F = 0.81 * 9.82 and t = 0,34s = 2,70kgm / s. I have observed that the ball bounces about 43% of the height at which it is released from. How can I link to such impulse and power?

But what shall I write in the discussion? Why the result as it gets, aiming for an A, it must have the nuance and detail, but gets nowhere ..

**2.**mv^2=mgh

p = mv

Imp = F*t

F = mg

**3.**I figured out the momentum via

**, where I got the speed. I got the impulse through F = 0.81 * 9.82 and t = 0,34s = 2,70kgm / s. I have observed that the ball bounces about 43% of the height at which it is released from. I must discuss why the result is as it is? I truly have no idea.**

**mv^2=mgh**
