A 1400-N crate rests on the floor. A) How much work is required to move it at constant speed 5.0 m along the floor against a friction force of 330 N. B) How much work is required to move it at constant speed 5.0
To the person above, I tried 1600 J before, but it's saying "Review your calculations; you may have made a rounding error or used the wrong number of significant figures". I don't know why it's wrong since it is 2 significant figures...
Nvm. It wanted me to round up instead of down. The correct answer for A is 1.7 kJ and B is 7.0 kJ.
