a) In periodic motion, it is often interesting to investigate the harmonic motion of an object. The decrease in amplitude caused by dissipative force is called damping, and the corresponding motion is called damped oscillation. Damped oscillation is governed by the following equation, where is the angular frequency of oscillation, A is the initial amplitude of the oscillation, m is the mass of an object, b is a constant that describes the strength of the damping force, t is time in seconds, h is the ratio between a force constant k and the mass m: where x(t) = Ae sin(at + p) If = 60°, A = 4, v = 2m @= h b² 4m² b = 0.25, create a plot x(t) for 0≤t≤ 15, with h = 4. Label all the axes, 2m include gridlines and provide a title in your plot.

2) Two objects with equal mass and equal and opposite velocity collide with each other. Find the relationship between angle of impact and absolute impulse experienced by each object. Note any angles that have special characteristics. This is an abstract problem where we will derive a general solution valid for any two masses, any two equal and opposite initial velocities and any angle of impact. You may assume the shape of the object plays no part in the outcome of the collision.
