# How much work is required to lift the load of the way up the shaft if a cable that weighs kg/meter is lifting a load of 150 kg that is initially at the bottom of a 50 meter shaft?

Since you provided no number, let's say the cable is 2 kg/m. You can fill in your own number in the second equation below.

To calculate the work required to lift the load up the shaft, you can use the formula:

Work = Force × Distance

First, calculate the force exerted by the cable, which is equal to the weight of the load plus the weight of the cable itself:

Force = (Weight of load + Weight of cable) × gravity

Weight of load = 150 kg Weight of cable = kg/meter × length of cable Length of cable = shaft height = 50 meters Gravity = 9.8 m/s²

Then, calculate the total distance the load is lifted:

Distance = Shaft height = 50 meters

Now, plug these values into the formula:

Work = (Force) × (Distance)

Finally, solve for the work.

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.
