Question

The K. E to a body is doubled it's momentum will.?

Answer 1

ke means kinetic energy

Answer 2

Kinetic energy is equal to K . E = 1 / 2 m * v^2

Momentum is directly proportional to velocity if mass is kept constant.

Momentum = mass * velocity

If kinetic energy is doubled its

Velocity will also increase four times

* Momentum will also be doubled *
