5. A diver plunges head first into a diving pool while travelling at 28.2 m/s. Upon entering the water, the diver stops within a distance of 4.00 m from the diving board. Consider the diver to be a single point located at her centre of mass and assume her acceleration through the water to be uniform. a Calculate the average acceleration of the diver as she travels through the water. b How long does the diver take to come to a stop? What is the speed of the diver after she has dived for 2.00 m.
