Problem 4. A particle of mass m is attached to two nearby walls by springs, each of which has spring constant k, as in the figure below. When the particle is situated at the midpoint between the two walls, both springs are un-stretched. The mass is now pulled to the right by an amount A, and then at time t = 0 is released from rest (i. e., with no initial velocity). Ignore gravity, and ignore any motion in the transverse (i. e., y ) direction. (20 points total) (a) By applying Newton's laws of motion, find the differential equation that governs the subsequent motion of the particle. (10 points) (b) What is x(t) for this particle? What is the frequency of oscillation of this particle, ω, as a function of k and m? (5 points) (c) What is the period of oscillation, T? (5 points)

A bar with a length of L = 0.50 m slide without friction on horizontal rails, as shown in Figure 1. There is a uniform magnetic field of B = 2.0 T directed into the plane. At one end of the rails, there is a battery with an emf of ε = 15 V and a switch. The bar has a mass of 0.90 kg and a resistance of 5.0 Ω, while any other resistance in the circuit is negligible. The switch is closed at t = 0. Figure 1 (a) Plot the speed of the bar as a function of time. (b) What is the acceleration of the bar immediately after the switch is closed? (c) What is the acceleration of the bar when its speed reaches 2.0 m/s? (d) What is the terminal speed of the bar?

A bullet is fired horizontally at a stationary 7.0 kg target. The target sits on a frictionless horizontal surface and is connected to a spring on the backside of the target. The spring has a spring constant of 5000 N/m. The 11.0 g bullet is traveling horizontally at 675 m/s the moment before it strikes the target. After 1 ms, the bullet is embedded into the target and begins to oscillate. Ignore air resistance. (a) Determine the speed of the block immediately after the collision. Hint: what quantity is conserved during the collision? (b) Find the period and amplitude of the resulting simple harmonic motion. (c) Find the initial phase of the resulting simple harmonic motion. Hint: note that the block is at its equilibrium position x = 0 at t = 0. (d) On three separate graphs, plot the position vs. time, velocity vs. time, and acceleration vs. time for the system starting when the bullet is fully embedded into the target. Be sure to clearly label your axes and the scale of each graph. (e) On a single graph, plot the potential energy, kinetic energy, and total mechanical energy as a function of time for the system starting when the bullet is fully embedded into the target. Be sure to clearly label your axes and the scale of your graph.
