A vertically jet of water coming out of a nozzle with velocity `20 m//s` supports a plate of mass M stationary at a height `h = 15 m`, as shown in the figure. If the rate of water flow is 1 litre per second, the mass of the plate is (Assume the collision to be perfectly inelastic).

A particle of mass m strikes a disc of radius R and mass m with a speed u as shown in the figure. What is the speed of the particle just after the collision if the collision is perfectly inelastic ?

A uniform square plate of mass m is supported with its plane vertical as shown in the figure. Assume the centre of mass is on a horizontal the passing through A. If the cable at B breaks then just after that the angular acceleration of the plate is

A ball is projected with velocityd of 20sqrt(2) m/s at an angle of 45^(@) with horizontal and at the same instant another plate is rotating with constant angular velocity omega=(pi)/(4) rad/sec in vertical plane as shown in the figure ( assume the length of plate is sufficient for collision to take place). If the mass of the plate is much larger than the mass of the ball, the plate is initially in horizontal position and collision is perfectly elastic, then choose the correct statement (s)

Two particles of mass 1 kg and 2 kg are moving with speed 2 m/s and 5 m/s as shown in the figure, they collides perfectly inelastically. And second particle come to rest after collision. Find (a) Their final velocity (b) Loss in kinetic energy

An object of mass 40kg and having velocity 4 m//s collides with another object of mass 60 kg having velocity 2 m//s . The loss of energy when the collision is perfectly inelastic is
