The spring constant of a spring that takes 385 J of work to stretch 0.250 m.
What is 12300 N/m?
Even though this force can be present, it does no work on an object moving in uniform circular motion because it acts perpendicular to the displacement.
What is centripetal force?
The work done by the force of friction if the force of friction is 35 N and the displacement is 2.0 m.
What is -70. J?
The velocity of a 4.00 kg object that had a net work of 135 J performed on it.
What is 8.22 m/s?
The potential energy of a system consisting of a vertical spring with spring constant 200 N/m with natural length 0.5 m that is compressed to a length of 0.4 m.
What is 1 J?

What is 1080 N/m?
A roller coaster reaches its highest point before plunging down a steep drop. At that instant, the coaster has this type of energy at a maximum, while this other type is at a minimum.
