Stanley the horse is pulling a loaded cart. He generates a power of 15 kW while pulling the cart for 2 minutes. Calculate the work done by Stanley, in kilojoules.

Sure, here's how you can calculate the work done by Stanley:

Step 1: Convert the time from minutes to seconds because the standard unit of time in physics is seconds. There are 60 seconds in a minute, so 2 minutes equals 120 seconds.

Step 2: Use the formula for power, which is Power = Work/Time. We can rearrange this formula to find work: Work = Power x Time.

Step 3: Substitute the given values into the formula. Power is 15 kW (but we need to convert it to watts, so it's 15000 W) and Time is 120 seconds.

Work = 15000 W x 120 s = 1800000 Joules.

Step 4: Convert the work from Joules to kilojoules. 1 Joule = 0.001 kilojoules, so 1800000 Joules = 1800 kilojoules.

So, Stanley did 1800 kilojoules of work.
