The spring in the figure below is stretched from its equilibrium position at x = 0 to a positive coordinate x0. The force on the spring is F0 and it stores elastic potential energy PEs0. If the spring displacement is quadrupled to 4x0, determine the ratio of the new force to the original force, Fn F0, and the ratio of the new to the original elastic potential energy, PEsn PEs0. HINT (a) the ratio of the new force to the original force, Fn F0 (b) the ratio of the new to the original elastic potential energy, PEsn PEs0

A spring (which behaves linearly both in tension and compression) when tested vertically in isolation, as shown in Figure 1, is found to stretch by x0 cm when it supports a mass of m1 kg. Figure 1 The spring extends by x0 cm when supporting an m1 kg mass The spring, along with a damper, is then attached horizontally to a trolley of mass 1360 kg, which is constrained to move only in the x-direction (see Figure 2). The spring is stretched some distance from its equilibrium position before being released. (a) (b) Figure 2 (a) A frictionless trolley is attached by a spring, with spring constant k and a damper with a damping coefficient χ. The trolley is shown in its natural rest position with its left-hand face at x = 0. (b) Free body diagram for the trolley shortly after being pulled to the right then released, with the spring under tension so, at this instant, its velocity is in the negative x-direction. (For clarity the damping force and normal reaction forces have been shown as acting at the point of their arrows - the spring force and weight are shown as acting at the tail of their arrows.)

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.

The launching mechanism of a toy gun consists of a spring of unknown spring constant, as shown in the figure below. If the spring is compressed a distance of 0.130 m and the gun fired vertically as shown, the gun can launch a 18.0-g projectile from rest to a maximum height of 21.0 m above the starting point of the projectile. a (i) (a) Neglecting all resistive forces, describe the mechanical energy transformations that occur from the time the gun is fired until the projectile reaches its maximum height. (b) Neglecting all resistive forces, determine the spring constant. (c) Neglecting all resistive forces, find the speed of the projectile as it moves through the equilibrium position of the spring (where x = 0 ), as shown in Figure (b).
