Question

A man throw a ball weighing 500g vertically upwards with speed of 10ms-1find its initial momentum

Answer 1

Answer:

5kgm/s

Explanation:

500g=0.5kg

Initial momentum = Product of mass multiplied by Velocity

P=0.5kg*10m/s

P=5kgm/s

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.
