Must use only the work-energy theorem, conservation of energy, and/or conservation ofmomentum. A wooden block whose mass is 50.0 kg is pressed against a spring that stores 370.0 J of energy. Thesystem is released from rest and the block slides across a horizontal floor a distance of 4.60 m beforecoming to a stop. What is the speed of the block when it is 2.00 m from where it started?
