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

mv = 1/2 m v v
v = 2 m/s
velocity is 2 Meyer per second
v = 2 m/s
velocity is 2 Meyer per second
