Question

if the velocity of the body is doubled with mass of body reduced to 1/4 times of initial mass then what will be the change in linear momentum of the body.

Answer 1

Answer:

It will be half of initial linear momentum

Explanation:

As we know p=mv

Now Let initial momentum be P1

and New momentum be P2

Then P1=Mv

And P2=(M/4)(2v)

or

P2=Mv/2

Or

P2=P1/2
