Using and atwood machine with masses m1 and m2 at first, Ask an Expert

Academics

Q1. An air track has a block with a height h=12.0 cm under one support. The other support is 3.50 m away. What is an angle of inclination theta?

Q2. Using and Atwood machine with masses m1 and m2, at first with m1 a distance 2h above m2, what is the speed of either mass they pass each other? Make use of energy to solve (hint they cross halfway between the starting positions of the two masses).
