Two identical balls of equal masses A and B are lying on a smooth surface as shown in figure. Ball A hits the ball B (which is at rest) with a velocity v= 16 m/s. What should be the minimum value of coefficient of restitution between A and B so that B just reaches the highest point of inclined plane : (g=10m/s^2 )

A ball of mass 1kg is attached to an inextensible string. The ball is released from the position shown in figure. The impulse imparted by the string to the ball immediately after the string becomes taut. (Take g=10m/s^2) Two particles of same mass m moving with velocities u1 and u2 collide perfectly inelastically. The loss [...]
A particle of mass m moving with a velocity u makes an elastic one-dimensional collision with a stationary particle of mass m establishing a contact with it for extremely small time. T. Their force of contact increases from zero to F0 linearly in time T/4, remains constant for a further time T/2 and decreases linearly from F0 to zero in further time T/4 as shown. The magnitude possessed by F0 is.
