Question

Calculate the momentum of a ball of mass 70gm moving with velocity of 20m/s

Answer 1

We know:

momentum =mass*velocity.

Convert: 70g to kg.

1g=0.001kg

70g=70*0.001kg

=0.07kg.

Now:

momentum=0.07kg*20m/s

=1.4kgm/s

ANSWER: 1.4kgm/s

Thanks.

Answer 2

Given mass of ball = 70gm=0.070Kg
velocity=20m/s
momentum (p)=m*V
= 0.070*20
=1.40kgm/s
