a ball of mass m1 and a block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass. the block lies on a frictionless incline of angle theta.

(a) draw the free body diagrams

(b) express newton's second law in component form

(c) find the magnitude of the acceleration of the two objects and the tension in the cord

(d) find the angle theta of zero acceleration for m2 = 2m1

(e) what's the magnitude of the tension at the condition of (d)

the gravitational acceleration is g.
