Two objects are connected by a massless string running over a frictionless ideal

Question

Two objects are connected by a massless string running over a frictionless ideal pulley. Object A has twice the mass of object B. Object A is held above object B and released. a) Describe the motion of objects A and B. b) Draw free body diagrams for each object A and B. c) If the mass of object A is Ma and the mass of object B is Mb, what is the acceleration? d) What is the tension in the string? e) What is the weight of object A? f) What is the force on object A? g) How does the force on object A compare to its weight?

Explanation / Answer

m1 =mass of object B

m2 =mass of object A

The direction of weight is always down, so the direction of all mg
