Question

If the linear momentum of a sphere is tripled.Its kinetic energy will become
1) Twice
2) Four times
3) Eight times A) Nine times​

Answer 1

Answer:

Momentum is directly proportional to velocity. If the momentum of an object is doubled, but its mass does not increase , then its velocity is doubled. IF momentum of a body is doubled then its kinetic energy becomes 4times it's initial value.
