A stationary particle explodes into two particles of masses 300 g and 250 g which movein opposite directions with velocities v1m/s and v2m/s respectively. Find the ratio oftheir kinetic energies

Two particles moving in opposite direction collide inelastically. The velocity of the firstparticle before the collision is 6 m/s and the second particle is 12 m/s. After collision,both particle moves with a common velocity of 3 m/s in the direction of first particle.Find the ratioof the kinetic energy of the first particle to that of the second particle before the collision

Find the ratio of velocities of two equal masses in an inelastic collision when one of themasses is stationary (Note : Express your answer in terms of coefficient of restitution e)

Two particles of masses m1 and m2 have equal linear momenta. The ratio of their kinetic energy

A 100 kg mass, initially at rest, is blown apart into two 50.0 kg pieces. After the blast, the two masses are moving apart with a relative velocity of 100 m/s. The total kinetic energy after the explosion is

A 1.1 object traveling east at 21 m/s collides with a 4.5 kg object traveling west at 10 m/s. After the collision, the 1.1 kg object has a velocity 3 m/s to the west. How much kinetic energy was lost during the collision?
