Two objects are connected by a string that passes over a frictionless pulley as shown in the figure. Assume the incline is frictionless and take m1=2.00kg, m2=6.00kg and theta=55.0 degrees. (a) Draw free-body diagrams of both objects (b) find the magnitude of the acceleration of the objects (c) the tension in the string, and (d) the speed of each object 2.00s after it is released from rest
