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 plasticcube of mass 0.5 kilogram slides across the table at a speed of 26meters per second and strakes the ball, causing the ball to leavethe table in the direction in which the cube was moving. The figurebelow shows a graph of the force exerted on the ball by the cube asa function of time.a) Determine the horizontal velocity of the ball immediately afterthe collision.b) Determine the following for the cube immediately after thecollision.i. its speedii. its direction of travel (right or left), if movingc) Determine the kinetic energy dissipated in the collision.d) Determine the distance between the two points of impact of theobjects with the floor.
