  • 2. A spring whose coefficient is k is compressed by length d and a block of mass m is placed right next to the end of the spring. When the spring is released, the block acquires a velocity and keeps on moving along a horizontal smooth surface until it reaches an inclined plane whose angle is θ and whose coefficient of friction with the block is μ. It travels up the inclined plane for a while before reaching maximum height.

  • a) What is the change of the kinetic energy of the block?

  • b) What is the change of the potential energy of the spring?

  • c) Whatisthechangeofthegravitationalpotentialenergy?

  • d) What is the change of the total energy of the system?

  • e) What is the work done by non-conservative forces?

  • f) Use these results to find the maximum height h as a function of the other variables.
