  • Conservation of energy in a mass-block system

    Write the conservation of energy on the rough surface. 3. The work lost due to the friction is mu*mg*x 4. The amount of initial energy is the same in both cases.

  • What is the speed of the block just before it hits the spring?

    Let's take it from a conservation of energy approach: At first, just as the block touches the spring, it has a certain amount of energy, E1, composed of gravitational potential energy due to its height, and kinetic energy due to its downward velocity

  • Combining Conservation Laws

    block stops, its final kinetic energy is zero and conservation of energy requires that the block's initial kinetic energy will be completely converted to the elastic energy stored in the spring.

  • Springs and Slopes

    The key point of this problem is the conservation of energy.
