To calculate work done on an object, a. multiply the force in the direction of motion by the distance the object moved b. multiply all forces applied to the object by the distance the object moved c. divide the force in the direction of motion by the distance the object moved d. divide the distance the object moved by the force in the direction of motion

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.)
