Abaseball is thrown directly upward at time t=0 and is caught again at time t=5s. assume that air resistance is so small that it can be ignored and that the zero point of gravitational potential energy is located at the position at which the ball leaves the thrower's hand. the points for part a are (0,100) (1,36) (2,4) (2.5,0) (3,4) (4, 36) (5,100). based on the graph of kinetic energy given (the points), sketch a graph of the baseball's gravitational potential energy. give specific points.
