Question

4. The momentum of particle is numerically equal to its KE What is the velocity
of the particle?
​

Answer 1

Answer:

The answer to your question is 2.

Explanation:

We know that,

Linear Momentum = Mass × Velocity

P = M × V

We also know that,

KE = 1 / 2 × MV²

In this case,

mv = 1 / 2 × MV²

v² - 2v = 0

v ( v - 2 ) = 0

∴ v = 0 or v = 2

This is a trivial case.

∴ v = 2 is the answer.

Hence, the velocity of the particle is 2 m/s.

Hope helps!
