Question

what is the momentum of a bicycle of mass 20kg when it is at rest? what is its momentum when it moves at a speed of 2 m/s​

Answer 1

Answer:

when it is in rest momentum is zero

when it moving with velocity of 2m/s

Momentum is mv=20*2

=40kg.m/s

Answer 2

Answer:

momentum = mv

when the body is at rest then v= 0 and hence momentum will also be 0 .

then if it is moving with 2 m/s then

momentum= 20 × 2 = 40 kg m/s
