Question

A body moving with velocity v has momentum and kinetic energy numerically equal what is the value of v

Answer 1

p=mv
k.e=1/2mv2
so v= 2

Answer 2

Answer:

Velocity, v = 2 units

Explanation:

It is given that, a body moving with velocity v has momentum and kinetic energy.

The momentum of an object is mathematically equal to the product of mas and velocity with which it is moving. So, p = m v

The kinetic energy is possessed due to the motion of object. Mathematically it can be written as, $KE=\dfrac{1}{2}mv^2$

According to question, $p=KE$

$mv=\dfrac{1}{2}mv^2$

$v=2\ units$

So, the velocity of moving body is 2 units.
