# The kinetic energy of an object with a mass of #1 kg# constantly changes from #126 J# to #702 J# over #9 s#. What is the impulse on the object at #5 s#?

Cannot be answered

Therefore, we must be clear about which 5s we are referring to in order to get the impulse's absolute value.

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.
