1. An object of mass 6-kg was pulling up on a mass of 3-kg sitting on an inclined plane(40 degrees) with a string and a tension T. Assuming that the system was going counterclockwise(upon the incline0 and assuming that the incline is frictionless, calculate: a. The acceleration of the system. b. The tension in the string.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
