Question: A baseball is thrown directly upward at time t=0 and is caught again at time t=5s. Assume that airresistance is so small that it can be ignored and that the zeropoint of gravitational potential energy is located at the positionat which the ball leaves the thrower's hand.
a. Sketch a graph of the kinetic energy of the baseball.
b. Based on the graph of kinetic energy, sketch a graph of thebaseball's gravitational potential energy.
c. Based on the kinetic and potential energy graphs, sketch a graphof the baseball's total energy.
