PHYS 201 Midterm: PHYS 201 TAMU 201Fall 11 Exam 2
Document Summary
No work needs to be shown and no partial credit will be given. (6 pts) 1. A block with mass 10. 0 kg is sliding due east on a horizontal surface. The forces on the block are gravity, the normal force exerted on the block by the surface and the kinetic friction force exerted by the surface. Point b is 5. 0 m due east of point a. At point a the block has speed 6. 0 mis and at point b the block has speed 4. 0 mis. Blocks a and b are initially at rest on a horizontal frictionless surface with a spring of negligible mass compressed between them. Block a has mass 5. 0 kg and block b has mass 20. 0 kg. The spring is released and the blocks move off in opposite directions. Blocks a and b are moving toward each other on a horizontal frictionless surface.
