Question

a man throws a ball weighing 500g vertically upwards with speed of 15m/s
1)find it's untilintial momentum 2) find its momentum at the highest point if it's flight​

Answer 1

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 np=mass×velocity.
