A mass of 0.5 kg moving along a horizontal frictionless surface encounters a spring having k = 200 N/m. The mass compresses the spring by 0.1 meters before reversing its direction. Consider the total time the mass is in contact with the spring. What is the total impulse delivered to the mass by the spring? (Let the initial direction of the mass's motion be the positive direction.)

Suppose that a 0.20kg is oscillating at the end of Spring upon a frictionless horizontal surface. The Spring can be both stretched and compressed and has a Spring constant of 240N/m. It originally stretched a distance of 12 cm from its equilibrium. What is the maximum velocity max that the mass will reach in its oscillation?

An object with mass 4.0 kg is sliding on a horizontal, frictionless surface at speed 11.5 m/s. This object is moving in the positive x-direction. A second object, having mass 5.55 kg, is sliding on the same surface at speed 15.5 m/s. The second object is moving in a direction 75 degrees counterclockwise from the positive x-direction. If the objects stick after impact how fast would it move?
