Question

Linear momentum of a particle of mass 100 gram is 1 kg metre/s . Find its velocity.​

Answer 1

We know that,

• Momentum = Mass × velocity

From question,

• Mass = 100 g = 100/1000 = 0.1 kg
• Momentum = 1 N

Now, just put all the values in the formula,

• p = mv
• 1 = 0.1 × v
• 1/0.1 = v
• 10 = v

Thus, the velocity of the particle is 10 m/s.
