Question

What is the momentum of a bycycle of mass 20 kg when it is at rest what is the momentum when it moves at a speed of 2m/s

Answer 1

Answer:

40 newton - second

Explanation:

the formula u need to use is =

P = m× v

P = momentum

P = 20 × 2 = 40

Answer 2

Explanation:

momentum= mass×velocity

i.e p=m×v

(i) m= 20 kg and v= 0m/s (at rest)

p= 0 kg m/s

(ii) m= 20 kg and v=2m/s,

p= 20×2 =40 kg m/s
