8 20 Pts In The Diagram Below Two Identical Blocks Are Connected Via A Massless String The String Is Pulled Across 1 (62.84 KiB) Viewed 33 times

8. (20 pts) In the diagram below, two identical blocks are connected via a massless string. The string is pulled across a pulley with negligible mass. The angle p is equal to 60°. The portion of the string between the pulley and the block on the right is held horizontal. Initially, both blocks are at rest and the tension in the string is zero. The second block is then released and begins to swing downward. After it has swung through an angle = 20°, the first block begins to slide up the ramp. What is the coefficient of static friction , between the block and the ramp? I Hint: The tension in the string is uniform since the pulley has negligible mass.
