10PRACTICE PROBLEM
A lab bench has two sections: The first section is frictionless while the second section has a kinetic friction coefficient of 0.20 between an experimental block and the bench. A 4.20 kg block is launched on the frictionless section using a compressed piston whose spring constant is 150 N/m. If the piston is pushed (compressed) by 25cm to launch the block, calculate the length covered by the block on the rough surface before it goes to rest. Use the work-energy theorem.
