After an head on elastic collision between two balls of equal masses, one is observed to have a speed of `3m//s` along the positive x-axis and the other has a speed of `2m//s` along the negative x-axis. What are the original velocities of the balls?

Two balls of equal mass have a head-on collision with speed 6 m//s . If the coefficient of restitution is (1)/(3) , find the speed of each ball after impact in m//s

A gun is mounted on a trolley which can move uniformly with speed v m//s along the x -axis. Two shots are find from the origin with the gun making an angle 30^(@) with the horizontal such that in the first case the trolley is moving along the positive x -axis and in the second case moving along the negative x - axis. The respective range of the projectile is 250 m and 200 m , along the x- axis. Find the velocity of the trolley in m//s . (Assume height of the trolley to be negligible)(given g=10m//s^(2) ).

A ball of mass m is moving with speed u to the left along the positive x-axis, toward the origin. It strikes another ball of mass m/4 at rest at the origin. After collision the incoming ball is reflected back to the right an angle of 37^(@) to the positive x-axis with a speed of m/5. Find the speed,and direction of motion of the other ball.
