Question

The momentum of a particle is numerically equal to it's kinetic energy . What is the speed of the particle

Answer 1

HEY BUDDY

HERE'S THE ANSWER..

_______________________________

# Momentum of a particle is equal to it's kinetics energy

We know

=> Momentum = mass × velocity

=> Momentum = m × v

We also know

=> Kinetic Energy = ( m v^2 ) / 2


Now according to question

=> m × v = ( m v^2 ) / 2

=> 2 × m × v = m × v × v

=> v = 2 m / s


So the velocity of particle is 2 m/s

Answer 2

mv = 1/2 m v v

v = 2 m/s

velocity is 2 Meyer per second
