4. The diagram represents the path of a ball that has been thrown upward. Discuss how the kinetic energy (KE), gravitational potential energy (GPE), and total
mechanical energy (ME) change between points A (where the ball is thrown from), B
(the highest point reached by the ball). Ind C (where the ball hits the ground). Ignore
friction between the ball and the air. (3 points)
