Question

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

Answer 1

kinetic energy=1/2 mV²
Momentum =mV
ATQ
kinetic energy = momentum
1/2 mV²= mV
1/2 V²= V
V²/V= 2
V=2m/ s
hence the velocity V at which Momentum and kinetic energy are numerically equal is 2 m/s
