Parker is a 56 kg pole vaulter and after successfully completing a vault, her center of mass achieves a maximum peak of height of 4.6 meters after pole-vaulting over the crossbar set at that height. She lands on a thick crash pad and when she first makes contact with the mat, her center of mass is 0.9 meters above the ground. During her impact with the mat, the mat undergoes a maximum compression at the point when her vertical velocity reaches 0 m/s and her center of mass is 0.3 meters from the ground. d) What is the work done by the crash mat on Parker during the landing in Joules to allow Parker to come to a complete stop? e) What is the magnitude of the average force in Newtons exerted by the mat on Parker to allow her to come to a stop during the landing of the vault?
