A student does 60 joules of work pushing a 3.0 kilogram box up the length of a ramp that is 500 centimeters long. What is the magnitude of the force applied to the box to this work?

Answer 1

#F = (60J)/(0.5m) = 120N#

This question attempts to confuse us by giving more information than necessary to answer the question. We need to remember that work is simply force times the distance it is applied over:

#W=F*d#

Therefore,

#60J = F*0.5m#

so solving for the force we get:

#F = (60J)/(0.5m) = 120N#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
