Elastic collision between cube and ball on a table

[dbb2112]

A 5 kilogram ball initally rests at the edge of a 2 meter long, 1.2 meter high frictionless table. A hard plastic cube of mass .5 slides across the table at a speed of 26 meters per second and strikes the ball, causing the ball to leave the table in the direction in which the cube was moving.

a. Determine the total impulse given to the ball.
b.Determine the horizantal velocity of the ball immediately after the collission.
c.Determine the following for the cuble immediatley after the collision.
i. its speed
i. its direction of travel if moving
d determine the kinetic energ dissipated in the collision
e. determine the distance beween the two points of impact of the objects with the floor
