Textbook Question
Chapter 19, Problem 10E
The enlarged circular inset in Fig.19.11 shows how the positive sodium (Na+) ions in seawater are accelerated out the rear of the submarine to provide a propulsive force. But what about the negative chlorine (Cl-) ions in the seawater? Because they have charge of the opposite sign, aren't they accelerated forward, resulting in a net force of zero on the submarine? Explain.

- A bungee jumper plans to bungee jump from a bridge 64.0 m above the ground. 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_forward9 V 300 Ω www 100 Ω 200 Ω www 400 Ω 500 Ω www 600 Ω ww 700 Ω Figure 1: Circuit symbols for a variety of useful circuit elements Problem 04.07 (17 points).

(Enter your answer in m.)arrow_forwardTruck 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.
