From what minimum height `h`must the system be released when spring is unstretches so that after perfectly inelastic collision `(e =0)` with ground, `B` may be lifted off the gound: (Spring constant `=k)`

A tennis ball is released from height h above ground level. If the ball makes inelastic collision with the ground, to what height will it rise after third collision

A block A of mass m is give a velocity v_(0) towards another block B of sae mass B . Is attached to an ideal spring of spring constant K . A makes a head on perfectly inelastic collision with B . Answer the following two questions: Q. Let the collision takes place at time t=0 choose the instant (s), when the spring is in its natural length.

A 2kg mass is attached to a spring of force constant 600 N//m and rests on a smooth horizontal surface. A second mass of 1kg slides along the surface toward the first at 6m//s . (a) Find the amplitude of oscillation if the masses make a perfectly inelastic collision and remain together on the spring. what is the period of oscillation ? (b) Find the amplitude and period of oscillation if the collision is perfectly elastic. ( c) For each case , write down the position x as a function of time t for the mass attached to the spring, assuming that the collision occurs at time t = 0 . What is the impulse given to the 2kg mass in each case ?

mass ‘m’ is projected vertically upwards with a speed ‘u’ and at the same instance another particle of mass ‘m’ is released from height ‘h’ vertically above the first particle. The two particles suffer a perfectly inelastic collision, and again reach a maximum height ‘h’ as one combined particle. What is the value of u?

Blocks A and B shown in the figure are having equal masses m. The system is released from rest with the spring unstretched. The string between A and ground is cut, when there is maximum extension in the spring. The acceleration of centre of mass of the two blocks at this instant is

There are two identical particles A and B. One is projected vertically upward with speed sqrt(2gh) from ground and other is dropped from height h along the same vertical line. Collision between them is perfectly inelastic. Find time taken by them to reach the ground after collision in terms of sqrt(h/g) .

In an arrangement shown , bob A on the left is pulled aside . It is then released and allowed to collide with other bob B which is at rest . A perfectly inelastic collision occurs and the system rises to a height h/4 . The ratio of the masses of the bobs is
