Question

A 1 kg mass is on a horizontal frictionless surface and is attached to a horizontal spring with a spring constant of 144 N/m. The spring's unstretched length is 20 cm. You pull on the mass and stretch the spring 5 cm and release it.

What is the position of the mass at 15 seconds? What is the magnitude of its velocity at that instant?

The mass spring system is now flipped vertically such that gravity must be included in the formulation of our governing equations. When the mass is resting (stationary) on the spring, how much is the spring compressed relative to its equilibrium position?

While the mass is resting at its equilibrium position on the spring, you hit the mass downward with a hammer. The average force of your hammer strike is 200 N and its duration is 1 ms. What is the period of the oscillations after the hammer strike?

After you strike the mass with a hammer, the impulse creates a nearly instantaneous velocity. What is the velocity of the block immediately after the hammer strike?

What is the maximum amplitude of oscillation of the mass after the hammer strike
