A student in a physics lab drops a ball of mass from a height of 1.5 m onto a force plate. The ball hits the force plate and rebounds upward. The student records the maximum height of the ball after it rebounds to be 1.1 m.

(a) The student uses their observations to correctly claim that the collision between the ball and the force plate is inelastic. Use the student's observations to justify their claim.

(b) Calculate the impulse exerted on the ball by the force plate.

The force plate records the following data for the magnitude of the force as a function of time for the 1 ms the ball was in contact with the force sensor. (see graph)

c) Does the force plate data provide a reliable measurement of the impulse exerted on the ball by the force sensor? Justify your answer
