Question

A man throws a ball of mass 0.5 kg vertically upwards with a velocity of 10 m/s . What will be it's initial momentum? What would be it's momentum at the highest point of it's reach?​

Answer 1

Answer:

-5

Explanation:

m =  0.5 kg

u = 10 m/s

V= 0m/s

initial momentum = mv-mu

                              = 0.5 x 0 - 0.5 x 10

                            = 0 - 5

 Momentum                            = -5 kg m/s

Kindly mark me as brainliest...

Answer 2

Initial momentum = mass x velocity = 0.5 x 10= 5kgm/s

Velocity at highest point = 0
Therefore final momentum = 0.5 x 0 = 0 kgm/s
