Carole is very tired and makes coffee. why would newton say that she must use her hand to put up the cup

newton say that she must use her hand to put up the cup because the work is equal to force times it distance, that is in the same direction of the force applied. if carole used her hand to put up the cup, then he is not applying any work because the displacement is not in the same direction of the force

The answer is B)  An object at rest will stay in at rest unless acted upon by an external force

Jared is correct because if you substitute a random number in for x 2 for example

2+10=12

2-10 doesn’t =12
