You lift a book slowly from the floor to the table. you then lift an identical book rapidly from the floor to the table. compared with the slow process, in the faster process your energy output [i. e., amount of energy transformed into gravitational energy] is greater.
work done is greater.
both of the above are correct.
power output is greater.
all of the above are correct.

Power output is greater

Explanation:

The books mentioned are all identical and the to which these books are being lift up is same in both the slow and the fast process.

Now , we know that the work done is the scalar product of force applied and its displacement and displacement in both the cases is same. Thus the net work done is also same.

If we talk about Power, then power is work done per unit time. It includes the time which was absent in work done and also the time here is in inverse proportion to power. Thus slower process will take more time and less power while faster one will take less time and more power.
