  1. You have a massless, ideal spring with an unknown spring constant ?. You hang the spring from the ceiling. You then attach a mass (? = 21.0 kg) to the spring, which causes it to fall a distance of 2.75 m before stopping immediately before hitting the floor.

    (a) What is ??
    (b) Graph gravitational potential energy versus the position of the mass above the floor. (c) Graph elastic potential energy versus the position of the mass above the floor.
    (d) Graph the kinetic energy of the mass versus the position of the mass above the floor.

A spring has a Hooke's law spring constant of 3.4 N/m. If you load it with 1.3 kg, how far will it extend from its equilibrium length? A spring 10 cm long extends 0.5 cm when a mass of 8 kg is hung from it. Suppose you made an similar spring of the same material, but twice as long. How much would it extend with the same mass? If you apply a force {f} newtons on a spring, and it...
