2. Calculate: The amount of work (W) done on an object is equal to the force (F) needed to lift the object (the object's weight) multiplied by the distance (d) the object is lifted: W=Fx d.

Use the weight of the ball that you calculated in activity B to determine how much work

would be required to lift the ball 2 meters above the zero position:
