The work done to raise a 5 kg weight by 7 m can be calculated using the formula for work, which is work = force × distance. In this case, the force is equal to the weight of the object, which is given by mass × gravitational acceleration (m × g). Gravitational acceleration is approximately 9.8 m/s^2. Therefore, the force required to lift the 5 kg weight is 5 kg × 9.8 m/s^2. Once we have the force, we multiply it by the distance lifted (7 m) to find the work done. So, work = (5 kg × 9.8 m/s^2) × 7 m. Calculating this gives us the total work done to raise the 5 kg weight by 7 m.

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.
