An object of mass m = 0.550 kg is lifted from the floor to a height of 3.50 m at a constant speed. Answer the following questions, show your work below and include units. (a) How much work is done by the lifting force? (b) How much work is done by the gravity of the object? (c) What is the net work done on the object? (d) What is the change in kinet energy the object? (e) If the object in this question is released from rest after it is lifted, what is its kinetic energy just before it hits the floor? What is its speed?
