Question

To practice Problem-Solving Strategy 10.1 Conservation of energy problems.

An ice cube of mass 50.0g can slide without friction up and down a 25.0degree slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 0.100m . The spring constant is 25.0N/m . When the ice cube is released, how far will it travel up the slope before reversing direction?

Part B

You should compile two lists: one of known quantities and one listing the variable(s) that are unknown. Identify the following variables as either known or unknown:

• m, the mass of the ice cube,
• k, the spring constant,
• x, the distance the spring compresses,
• h, the maximum height (measured vertically from the base of the slope) that the ice cube reaches,
• d, the maximum distance along the slope that the ice cube travels, and
• ?, the slope's angle of incline measured from the horizontal.
