Answer to Question #67138 in Mechanics | Relativity for Nikolas de Leeuw

Question

5. In the diagram, if m1 is 8.0 kg and m2 is 10.0 kg and the ramp is at a 35.0o angle find the acceleration of the masses assuming there is no friction. What would be the fk for the system to be at equilibrium?

6. A child shoots a 3.0 g bottle cap up a ramp 20o above horizontal at 2.0 m/s. The cap slides in a straight line, slowing to 1.0 m/s after traveling some distance, d. If fk is 0.40, find that distance.

7. Two monkeys with equal mass hang from the ends of a rope passing over a weightless, frictionless pulley. If one accelerates up the rope at 1.0 m/s2, what will happen to the other?
