A0.10- kg ball is thrown straight up into the air with
aninitial speed of 15m/s. find the momentum of the ball (a) at
itsmaximum height and (b) halfway to its maximum height.

(a)0,(b)1.061 kg-m/s

Explanation:

Given

mass of ball is 0.10 kg

Initial speed is 15 m/s

Maximum height reached by ball is h

final velocity =0

thus momentum of ball at maximum height is 0 as velocity is zero

For halfway to maximum height

where

v=10.61 m/s

Thus its momentum is

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement
