If an object is thrown in an upward direction from the top of a building 160 ft high at an initial speed of 30 mi/h, what is its final speed when it hits the ground? (Disregard wind resistance. Do not reflect negative direction in your answer.)

Energy stored in a moving object is called kinetic energy

If the object is moving at a constant elevation, kinetic energy may be the only energy possessed by an object. However, for an object moving down from a uphill location to a downhill location (that is, along a slope), the object possesses both the potential energy and the kinetic energy.
