A particle of mass m is moving with a uniform velocity v1.

Home » Mechanics » Laws of Motion » Question

A particle of mass m is moving with a uniform velocity v₁. It is given an impulse such that its velocity becomes v₂. The impulse is equal to

1. m[| v₂ | – | v₁|]
2. (1/2)m[v₂² - v₁²]
3. m[v₁ + v₂]
4. m [v₂ – v₁]

Correct Option: D

Impulse = final momentum – initial momentum = m (v₂ – v₁)
