(e) The force of the rope on the person parasailing is 5000 N. The boat pulls the person for a horizontal distance of 1000 m. The work done by the force of the rope on the person is not calculated by multiplying 5000 N by 1000 m. Explain how the work done by the force of the rope on the person could be calculated.
Humans can bite with a force of approximately 809 N. If a human tooth has the Young's modulus of bone, a cross-sectional area of 1.4 cm2, and is 1.9 cm long, determine the change in the tooth's length during an 8.09 ✕ 102 N bite.

A car is traveling 20m/s around a right hand curve. The passenger is at a radius of 5m and the driver is at radius of 6m. What is the centripetal acceleration felt by each?
A ball of mass m = 1.95 kg is released from rest at a height h = 72.0 cm above a light vertical spring of force constant k as in Figure [a] shown below. The ball strikes the top of the spring and compresses it a distance d = 8.30 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following. 27 h 11 (a) Find the speed of the ball just as it touches the spring. m/s 14T (b) Find the force constant of the spring. kN/m
