1. The problem statement, all variables and given/known data A 230-g air track glider is connected to a string hanging over a frictionless pulley. A 100-g mass hangs from the other end of the string. a) Draw force diagrams for the glider and the hanging mass. b) Find the acceleration of each. 2. Relevant equations F=ma a=m2/(m1+m2) x g 3. The attempt at a solution So I attempted solve this problem many ways. My textbook was not helping at all so I googled information on pulley systems. I got an example that fit this and I plugged in the numbers and got the answer to b. I don't need help with the free body diagram, just with understanding this. The equation I found was a= m2/(m1+m2)x g. So I plugged in the values: a=.1kg/(.23kg+.1kg) x g=2.97m/s2 The problem is, I have no clue how that formula works or why it was used. I initially tried to solve the problem by adding the forces and dividing by the total mass, but I was kind of lost. Any help is greatly appreciated.
