Chapter 5, Problem 2EP
From the preceding calculation, it should be obvious that to experimentally time the distance of fall for a dropped object is critical. To gain an appreciation of how the distance of fall varies with time, consider the daring experimenter shown in ● GL Fig. 5.1. Jo-Jo will illustrate the time-distance relationship of free fall by stepping off a high, vertical cliff with a timer in one hand and a marker in the other. For each second of fall, he makes a mark on the cliff face.
But wait. Jo-Jo wants you to determine how far he would fall during each second for the first 5 seconds. He requests you plot the results on a distance versus time graph for a visual display.
Oh, one other thing. He wants to open his parachute when reaching 60 mi/h. At what time, or between which seconds, should he do this?

A 105- and a 45.0-Q resistor are connected in parallel. When this combination is
connected across a battery, the current delivered by the battery is 0.268 A. When the
45.0-resistor is disconnected, the current from the battery drops to 0.0840 A.
Determine (a) the emf and (b) the internal resistance of the battery.

He plans to use a uniform elastic cord, tied to a harness around his body, to stop his fall at a point 6.00 m above the water. Model his body as a particle and the cord as having negligible mass and obeying Hooke's law. In a preliminary test he finds that when hanging at rest from a 5.00 m length of the cord, his body weight stretches it by 1.55 m. He will drop from rest at the point where the top end of a longer section of the cord is attached to the bridge. (a) What length of cord should he use? Use subscripts 1 and 2 respectively to represent the 5.00 m test length and the actual jump length. Use Hooke's law F = KAL and the fact that the change in length AL for a given force is proportional the length L (AL = CL), to determine the force constant for the test case and for the jump case. Use conservation of mechanical energy to determine the length of the rope. m (b) What maximum acceleration will he…arrow_forward

- Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as shown in the figure below. When the main leaf spring is compressed by distance yo, the helper spring engages and then helps to support any additional load. Suppose the leaf spring constant is 5.05 × 105 N/m, the helper spring constant is 3.50 × 105 N/m, and y = 0.500 m. Truck body yo Main leaf spring -"Helper" spring Axle (a) What is the compression of the leaf spring for a load of 6.00 × 105 N? Your response differs from the correct answer by more than 10%.
