Question

If the momentum of an object triples with the mass remaining constant, what happens to the velocity?

Answer 1

Answer:

If the momentum of an object triples with the mass remaining constant, the velocity of object becomes triple

Answer 2

Let the mass and the initial velocity be (m) and (v(i)) respectively.

∴ p(i) = mv(i)

Now, as per condition, p′ = 3p

Let the final velocity be = v(f)

⇒ m × v(f) = 3(mv(i))

⇒ v(f) = 3v(i)

So, the final velocity is 3 times the initial one.
