Two masses 1g and 4g are moving with equal kinetic energies. The ratio of the magnitudes of their linear momenta is _.
Correct answer: B. 1:2
- A. 4:1
- B. 1:2
- C. 0:1
- D. 1:6
Explanation
The kinetic energy and momentum are related as; K.E=P2/2m As mass and momentum are directly related, they will be related as;

About Linear Momentum
Linear momentum is the vector product of mass and velocity, p = mv, and changes when a net external force acts. Work includes impulse as the change in momentum, conservation of momentum in isolated systems, collisions and explosions, and the distinction between elastic, inelastic and perfectly inelastic collisions.
