A 200-g mass resting on a horizontal frictionless surface is attached to a spring of spring constant 35 N/m. It is given a quick blow with a hammer so that it moves away from its equilibrium position with an initial speed of 0.60 m/s.
(a) What is the amplitude (i.e. maximum displacement) of the resulting oscillations?
(b) What is the angular frequency of the oscillations?
(c) What is the period of the oscillations?
(d) Describe two changes that could be made to the system that would increase the period of the oscillations.

A bullet of mass 0.0022 kg initially moving at 496 m/s embeds itself in a large fixed piece of wood and travels 0.64 m before coming to rest. Imagine that an acceleration of the bullet is constant.
A 0.200 kg block is placed on a vertical spring (k = 5.80x 10^3 N/m) and pushed downward, compressing the spring 0.100 m. As the block is released, it leaves the spring and continues to travel upward. What height above the point of release will bl..
A 2 kg mass is pushed 0.5 m into a spring with spring constant 200 N/m on a frictionless horizontal surface. Upon release, the mass travels across the surface until it encounters a rough incline. The mass moves up incline and stops at a height of ..
