Question

The momentum of particle is numerically equals to its kinetic energy what will be the velocity of the particle

Answer 1

Given Kinetic Energy  = momentum    ----  (i) 

We know that K.E = 1/2 mv^2, Momentum = mv    ----------- (ii)

Apply (ii) in (i)

= 1/2 mv^2 = mv

= 1/2 m * v * v = mv

= 1/2 v = 1

v = 2

So, the velocity of the particle i.e v = 2.


Hope this helps!

Answer 2

Momentum = mv
Kinetic energy = 0.5mv^2

Both are numerically equal
mv = 0.5mv^2
v = 1/0.5
v = 2

Velocity of particle is 2 m/s (if taken in SI units)
