An elevator of mass M is pulled upwards by a cable; the elevator has a positive, but decreasing, velocity. What is the tension in the cable (neglecting the mass of the cable)

Less than

Explanation:

As the elevator is being pulled up the velocity is decreasing that means it has negative acceleration.

The force equation will be as follows

where

Here the value of is negative as the elevator is slowing down so the tension on the cable will be less than the actual weight of the elevator.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
