The car has a constant speed vM and passes x = 0 at t = 0. The police motor starts at x = 0 with constant acceleration ap at t = t1 (with t1 > 0 ). (a) Calculate the time t at which the motorist and the police are at the same position. (b) When the police wants to catch the car at position x = XC, what acceleration ap should he/she have? Express ap in Xc, vM and t1.

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.

An object oscillates with simple harmonic motion along with x axis. Its displacement from the origin varies with time according to the equation x = (4.00 m)cos⁡(πt + π/4) Where t is in seconds and the angles in the parentheses are in radians. (a) Determine the amplitude, frequency and period of the motion. (b) Calculate the velocity and acceleration of the object at time t. (c) Using the results in part(b), determine the position, velocity and acceleration of the object at t = 1.0 s (d) Determine the maximum speed and acceleration of the object.
