A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:

Consider an oblique elastic collision between a moving ball and a stationary ball of the same mass. Both the balls move with the same speed after the collision. After the collision, the angle between the directions of motion of two balls is x degree. Find the value of x.

A ball is projected from point A in horizontal direction with a velocity of u = 28 m//s . It hits the incline plane at point B and rebounds. Show that whatever be the coefficient of restitution between the ball and the incline, the ball will always hit the incline for the second time at a point above B (i.e., it will not hit the incline below B). Assume the incline to be smooth and take g = 10 m//s^(2) [sin 37^(@)=(3)/(5)]

Suppose a ball is projected with speed u at an angle alpha with horizontal. It collides at some distance with a wall parallel to y-axis. Let v_(x) and v_(y) be the components of its velocity along x and y-directions at the time of impact with wall. Coefficient of restitution between the ball and the wall is e . Component of its velocity along y -diection (common tangent) v_(y) will remain unchanged while component of its velocity along x -direction (common normal) v_(x) will become ev_(x) is opposite direction. The situation shown in the figure a small ball is projected at an angle alpha between two vertical walls such that in the absence of the wall its range would have been 5d . Given that all the collisions are perfectly elastic (for first and second problems), the walls are supposed to be very tall. The total time taken by the ball to come back to the ground (if collision is inelastic) is

Two balls with masses in the ratio of 1:2 moving in opposite direction have a head-on elastic collision. If their velocities before impact were in the ration of 3:1, then velocities after impact will have the ratio :
