A 5-kilogram ball intially rests at the edge of a 2-meter-long, 1.2-meter-high frictionless table, as shown above. A hard plastic cube of mass 0.5 kilogram slides across the table at a speed of 26 meters per second and strakes the ball, causing the ball to leave the table in the direction in which the cube was moving. The figure below shows a graph of the force exerted on the ball by the cube as a function of time.

(I did the part of the problem dealing with the graph finding the total impulse.)

I need help doing b and c

b.) Determine the horizontal velocity of the ball immediately after the collision.

c.) Determine the following for the cube immediately after the collision.

i. its speed

ii. its direction of travel (right or left), if moving

I was confused how to set up these two problems, is the collision elastic? How should I find the velocities immediately after the hit? Thank you for any help you can give!!!!
