Question

If the mass of the body is double its velocity become half

Answer 1

Explanation:

If the mass of a body is doubled and its velocity becomes half, then the linear momentum of the body will remain same.

Answer 2

Answer

Momentum = (mass)×(velocity)

According to question

Mass = 2m

velocity = 1/2v

Then

Momentum = (2m)×(1/2 v)

Momentum = (m. v) =(mass)×(velocity)

Hence Linear momentum remain same.
