A spherical ball A of mass 4 kg, moving along a straight line strikes another spherical ball B of mass 1 kg at rest. After the collision, A and B move with velocities `v_1 m s^(-1) and v_2 m s^(-1)` respectively making angles of `30^@ and 60^@` with respect to the original direction of motion of A. The ratio `v_1/v_2` will be

A spherical ball A of mass 4 kg, moving along a straight line strikes another spherical ball B of mass 1 kg at rest. After the collision, A and B move with velocities v_(1)ms^(-1) and v_(2)ms^(-1) respectively making angles of 30^(@) and 60^(@) with respect to the original direction of motion of A. The ratio (v_(1))/(v_(2)) will be

A ball of mass 100g moving at a speed of 12 m s^(-1) strikes another ball of mass 200 g at rest. After the collision both the balls move with a common velocity. Find the common velocity.

A ball of mass 1 kg moving with a velocity of "0.4 ms"^(-1) collides with another stationary ball. After the collision, the first ball moves with a velocity of 0.3ms^(1) in a direction making an angle of 90^(@) with its initial direction. The momentum of the second ball after the collision will be (in kg ms^(-1) )
