A body of mass m moving with velocity `3km//h` collides with a body of mass 2m at rest. Now, the coalesced mass starts to move with a velocity

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity

A moving body of mass m and velocity 3 km/hr collides with a rest body of mass 2m and sticks to it. Now the combined mass starts to move. What will be the velocity of the combined mass ?

If a body of mass m moving with velocity v collides with another body of mass m at rest. If e is the coefficient of restitution then find the ratio of final velocities of two bodies :

A body of mass m, moving with velocity mu collides elasticity with another body at rest having mass M. If the body of mass M moves with velocity V, then the velocity of the body of mass m after the impact is

A body of mass 5 kg moving with a velocity 10 m/s collides with another body of the mass 20 kg at, rest and comes to rest. The velocity of the second body due to collision is

A body of mass 4 kg moving with velocity 12 m//s collides with another body of mass 6 kg at rest. If two bodies stick together after collision , then the loss of kinetic energy of system is
