Question

A man throws a ball weighing 500g vertically upwards with speed of 10m/s. 1) what will be its initial momentum

Answer 1

hi,

HERE WE GO

GIVEN

mass (m) = 500g = 500/1000kg = 0.5kg

speed = 10ms^-1

Initial momentum (mu) = ?

momentum at highest point = ?

SOLUTION

Initial momentum = mu

= (0.5)(10)

therefore initial momentum = 5kgms^-1

REMEMBER

the body experiences zero velocity in its highest point.

so there v= 0

Momentum at highest point = m(0) = 0.5 (0)=0

HOPE IT IS HELPFUL :D

Answer 2

Answer:

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