A bungee jumper, mass 80 kg, falls from a bridge with a bungee cord secured to his ankles. He falls 20 m before the 17 m length of elastic bungee cord begins to stretch. The 3 m of rope above the elastic cord has no appreciable stretch. The man is observed to drop a total of 44 m before being projected upward. Neglect any energy loss and calculate: (a) The stiffness, k , of the bungee cord (b) The max velocity of the man during the fall. (c) The max acceleration of the man. Treat the man as a particle located at the end of the cord.

A baseball (radius = .0366 m, mass = .145 kg) is dropped from rest at the top of the Empire State Building (height = 1250 ft). Calculate (a) the initial potential energy of the baseball, (b) its final kinetic energy, and (c) the total energy dissipated by the falling baseball by com- puting the line integral of the force of air resistance along the baseball's total distance of fall. Compare this last result to the difference between the baseball's initial potential energy and its final kinetic energy. (Hint: In part (c) make approximations when evaluating the hyperbolic functions obtained in carrying out the line integral.) 2.9
A speedboat with a mass of 529 kg (including the driver) is tethered to a fixed buoy by a strong 28.3 m cable. The boat's owner loves high speed, but does not really want to go anywhere. So the owner revs up the boat's engine, makes a lot of noise, and runs the boat in circles around the buoy with the cable supplying all the necessary centripetal force. When the tension of the cable is steady at 12300 N, with what force is the boat's engine pushing the boat? Different physics textbooks treat drag force somewhat differently and use different formulas. For the present purpose, take the water's drag force on the boat to be (450 kg/m)×v2, where v denotes the boat's speed. Ignore any drag force on the cable. What is the force of the engine?
A69 A typical escalator in the London Under- ground rises at an angle of 30° to the horizontal. It lifts people through a vertical height of 15 m in 1.0 minute. Assuming all the passengers stand still whilst on the escalator, 75 people can step on at the bottom and off at the top in each minute. Take the average mass of a passenger to be 75 kg. (a) Find the power needed to lift the passen- gers when the escalator is fully laden. For this calculation assume that any kinetic energy given to the passengers by the escalator is negligible. (b) The frictional force in the escalator system is 1.4 x 10*N when the escalator is fully laden. Calculate the power needed to overcome the friction. Hence find the power input for the motor driving the fully laden escalator, given that the motor is only 70% efficient. (c) When the passengers walk up the moving escalator, is more or less power required by the motor to maintain the escalator at the same speed? Explain your answer. (0 & C, '90]

During the packaging process, a can of soda of mass m = 0.4 kg moves down a surface inclined 20° relative to the horizontal, as shown in the figure below. The difference between the initial height of the can and the final height of the can is dz = 2 m. The can is acted upor by a constant force R parallel to the incline and by the force of gravity. The magnitude of the constant force R is 0.05 N. Ignoring friction between the can and the inclined surface, determine the can's change in kinetic energy, in J, and whether it is increasing or decreasing. Let g= 9.8 m/s².

To apply Newton’s second law and the theorem of conservation of energy to solve kinetic problems. A bungee jumper wants to jump off the edge of a bridge that spans a river below. The jumper has a mass m, and the surface of the bridge is a height h above the water. The bungee cord, which has lengthL when unstretched, will first straighten and then stretch as the jumper falls.Assume the following: The bungee cord behaves as an ideal spring once it begins to stretch and has spring constant k. The jumper does not actually jump but simply steps off the edge of the bridge and falls straight downward. The jumper's height is negligible compared to the length of the bungee cord. Thus, the jumper can be treated as a point particle. Use g for the magnitude of the acceleration due to gravity. How far below the bridge, d, will the jumper eventually be hanging, once the jumper stops oscillating and comes finally to rest? Assume that the jumper does not touch the water.
