Question

Help.

A person pushes a giant boulder with a force of 50N for 10min. The boulder moves 0cm. Use what you know about force, work, and acceleration to explain what happened.

Question 33 options:

500J of work was done because the person pushed for 10 min


The boulder moved 10m because the person pushed for 10 min


The person did a lot of work because s/he pushed with a high force


No work was done because the boulder was not displaced

Answer 1

No work was done because the boulder was not displaced.

Step-by-step explanation:

Even if a person is pushing with a force of 50N and for 10 min, zero work is done and there's no acceleration. Zero work means when the force or displacement on the object is equal to 0 J, and since the boulder never moved it would be 0 J. If the person was pushing with 50 N or even higher and the the object didn't budge, the velocity hasn't changed from rest and that would mean no acceleration occurred.
