Question

you pick up a 3.8 kg can of paint from the ground a lift it to a height of 1.4 m. you hold the can stationary for half a minute, waiting for a friend on a ladder to take it. how much work do you do duting this time (when the can of paint is stationary)?

Answer 1

No work

Step-by-step explanation:

During the time of holding the can stationary, no work is being done by the person carrying the can.

The can is simply at rest.

• Work is done when a force is applied to move a body through a certain distance.

Work done = force x distance

In the instance given in this problem, only when the paint was lifted up is work done.

When the paint is stationary and being supported by the person, no work is done.
