Chapter 8.1, Problem 1bT
Suppose that the loop is now placed in the magnetic field of a solenoid as shown.
1. Determine whether there would be a current through the wire of the loop in each case below. if so, give the direction of the current. Explain in terms of magnetic forces exerted on the charges in the wire of the loop.
• The loop is stationary.
• The loop is moving toward the solenoid.
• The loop is moving away from the solenoid.
2. For each case above in which there is an induced current, determine:
• the direction of the magnetic moment of the loop. (Hint. Find the direction of the magnetic field at the center of the loop due to the induced current in the Loop. The magnetic moment is a vector that points in this same direction.)
• whether the loop is attracted toward or repelled from the solenoid.
•whether the force exerted on the loop tends to increase or to decrease the relative motion of the loop and solenoid.

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.

A spring is attached to an inclined plane as shown in the figure. A block of mass m = 2.71 kg is placed on the incline at a distance d = 0.285 m along the incline from the end of the spring. The block is given a quick shove and moves down the incline with an initial speed v = 0.750 m/s. The
incline angle is = 20.0°, the spring constant is k = 505 N/m, and we can assume the surface is frictionless. By what distance (in m) is the spring compressed when the block momentarily comes to rest?

- 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.
