In an inelastic collision of two bodies, the final kinetic energy is less than the initial kinetic energy of the system.

Q. A body of mass m moving with a speed v suffers an inelastic collision with another body of M at rest and sticks to it, the ratio of the final kinetic energy of the system to the initial kinetic energy is

Q. In a collinear collision, a particle with an initial speed $v_0$ strikes a stationary particle of the same mass. If the final kinetic energy is $50\%$ greater than the original kinetic energy, the magnitude of the relative velocity between the two particles, after collision, is

Q. In an inelastic collision, the kinetic energy after collision

Q. A 4 kg sphere moving with velocity of 4 m/s collides with an identical sphere of 2 kg moving with 2 m/s as shown. Final kinetic energy is less than initial kinetic energy. What type of collision is this?
