Question

a man throws a ball weighing 500g vertically upwards with a speed of 10m/s.

(a) what will be its inital momentum (b) what would be its momentum at the highest pont of flight ?

Answer 1

since i knw the answer of A i shall tell
m1=500g
=0.5kg
speed=initial velocity(u1)=10m/s

m1u1=0.5×10kg.m/s
=5kg.m/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.
