Question

10 kg ball is thrown straight up into the air with an initial speed of 15 m/s. what is the momentum of the ball?

Answer 1

Initial momentum of ball = Mass × Initial Velocity
= 10 kg × 15 m/s
= 150 kg m/s

Momentum of ball at maximum height = Mass × Velocity at maximum height
= 10 kg × 0 m/s
= 0 kg m/s
[∵ Velocity at maximum height of vertically projected up body is 0]

Answer 2

Given mass=10kg
And velocity=15m/s^
Momentum=M×V
=10×15
=150kgm/s
