A metal ball of mass `2 kg` moving with speed of `36 Km//h` has a collision with a stationary ball of mass `3 kg`. If ater collision, both the ball move together, the loss in Kinetic energy due to collision is :

A metal ball of mass 2 kg moving with a velocity of 36km//h has a head on collision with a stationery ball of mass 3 kg. If after the collision, the two balls move together, the loss in kinetic energy dur to collision is

A metal ball of mass 2 kg moving with a velocity of 36 km./h has a head on collision with a stationary ball of mass 3 kg. If after the collision the two balls move together, the loss in K.E. due to collision is :

A ball of mass 5 kg moving with speed 8 m/s collides head on with another stationary ball of mass 15 kg. If collision is perfecty inelastic, then loss in kinetic energy is

A ball of mass 5 kg moving with speed 8 m/s collides head on with another stationary ball of mass 15 kg. If collision is perfectly inelastic, then loss in kinetic energ is

A ball of mass 5 kg moving with speed 8 m/s collides head on with another stationary ball of mass 15 kg. If collision is perfectly inelastic, then loss in kinetic energ is

A ball weighing 4 kg and moving with velocity of 8 m/sec. Collides with a stationary ball of mass 12 kg. After the collision, the two balls move together. The final velocity is

A sphere of mass 2 kg moving at 36 km/hr collides head on with another sphere of mass 3 kg kept at rest . If after collision both spheres moves together then kinetic energy decreases by collision will be ……….
