A) A spring has a spring stiffness constant k of 100N/m . How much must this spring be compressed to store 35.0J of potential energy?

B) A 69-kg trampoline artist jumps upward from the top of a platform with a vertical speed of 5.2m/s.

How fast is he going as he lands on the trampoline, 2m below?

If the trampoline behaves like a spring of spring constant 7.4x10⁴N/m , how far does he depress it?

C)A ski starts from rest and slides down a 28?incline 55m long.

If the coefficient of friction is 0.090, what is the ski's speed at the base of the incline?

If the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level? Use energy methods.
