A block-spring system moves with simple harmonic motion and has an amplitude of A.
a. What is the magnitude of the displacement, x, when the kinetic energy equals three times the potential energy stored in the spring.
b. Suppose at a certain instant the kinetic energy is twice the elastic potential energy. Write an equation describing this situation, using only the variables for mass m, velocity v, spring constant k, and position x.
c. Using the results of parts a and b, and the conservation of energy equation, find the positions x of the object when its kinetic energy equals twice the potential energy stored in the spring (this answer should be in terms of A only)

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?
