Springs & Elastic Potential Energy Video Lessons

Example

# Problem: A block with mass 0.50 kg is forced against a horizontal spring of negligible mass, compressing the spring a distance of 0.20 m (the figure ). When released, the block moves on a horizontal tabletop for 1.00 m before coming to rest. The spring constant exttip{k}{k} is 100 N/m.What is the coefficient of kinetic friction k between the block and the tabletop?
