Springs & Elastic Potential Energy Video Lessons

Example

# Problem: An ice cube of mass 50.0 g can slide without friction up and down a 25.0° slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 0.100 m. The spring constant is 25.0 N/m. When the ice cube is released, how far will it travel up the slope before reversing direction?A) Identify the initial and final gravitational potential energies. Enter your answers, separated by a comma, in terms of some or all of the variables m, k, x, d, θ and the acceleration due to gravity g.B) Identify the initial and final elastic potential energies. Enter your answers, separated by a comma, in terms of some or all of the variables m, k, x, d, θ, and the acceleration due to gravity, g.
