Question

A 71.25 kg motorcycle is moving at a speed of 33.75 m/s towards west direction. What is the momentum
of the motorcycle?
​

Answer 1

Explanation:

mass = 71.25kg

Velocity = 33.75 m/s towards west

Momentum = Mass × velocity.

= 71.25×33.75 = 2404.7 kg-m/s

put an arrow on top towards left as it specifies in west direction

Answer 2

Answer:

The momentum of the motorcycle is 2404.7 kg-m/s towards west.

Explanation:

Given,

mass of motorcycle = 71.25kg

Velocity = 33.75 m/s towards west

Now,we know that,

Momentum = Mass x velocity

→ $p = mv$

      = 71.25 x 33.75 = 2404.7 kg-m/s

Direction is the same as velocity.

Therefore,the momentum of the motorcycle is 2404.7 kg-m/s towards west.
