Question

An object of mass 20 kg is moving with a velocity of 10 m/s. Its momentum will be:

• A. 2 kg.m/s
• B. 2000 kg.m/s
• C. 20 kg.m/s
• D. 200 kg.m/s

Answer 1

The correct option is (B) 200 kg.m/s

Given,

Mass of the body = 20 kg

Velocity of the body = 10 m/s

We know,

The momentum of a body is given by the product of the mass of the body and velocity.

So,

$MomentumP=Massm\times Velocityv$

Putting all the values

$P=20\times 10=200$ kg.m/s

Hence the momentum of the body is 200 kg.m/s
