Question

A student pushes a laptop cart down the hallway by applying 20 Newtons force. The student pushes it 10 meters and

then stops at the water fountain with the cart and haves a sip of water. While he drinks from the water fountain, what
type of work is being done to the laptop cart.

Answer 1

None.

Step-by-step explanation:

• By definition, work is a process that it happens when an applied force

causes an object to change its position, i.e. to have a displacement.

Since the laptop cart is at rest while he stops at the water fountain, no

net work done is on the laptop cart.
