Question

A man throws a ball weighing 500g vertically upwards with the speed of 10m/s, find (a) initial momentum. (b) its momentum at the highest point.

Answer 1

$p = mv$
you can use this formulas and refer to the picture above.

Answer 2

Answer:

1. Initial momentum is mu=0.5Kg×10m/s=5Kg−m/s

2. At highest point its velocity becomes zero so momentum will slo be zero as momentum p=mass×velocity.
