An object (3.7kg) is lifted 4.6 m above the ground and thendropped to the ground. What is the object's Pe at the top ofthe lift? How long will the object take to fall to the ground? Howfast will the object be going just prior to hitting theground? What Ke will the object have just before it hits theground? How much work did gravity do on the object?
