Question: A cyclist does 1500 J of work to climb a hill. If he takes 5 minutes, what is his average power output?

Options:

Correct Answer: 10 W

Solution:

Power = Work / Time = 1500 J / (5 * 60 s) = 5 W.

A cyclist does 1500 J of work to climb a hill. If he takes 5 minutes, what is his average power output?

A cyclist does 1500 J of work to climb a hill. If he takes 5 minutes, what is his average power output?

Step 1: Understand the problem. We need to find the average power output of a cyclist who does 1500 J of work in 5 minutes.
Step 2: Recall the formula for power. Power is calculated as Power = Work / Time.
Step 3: Identify the work done. The cyclist does 1500 J of work.
Step 4: Convert the time from minutes to seconds. Since there are 60 seconds in a minute, 5 minutes is equal to 5 * 60 = 300 seconds.
Step 5: Substitute the values into the power formula. Power = 1500 J / 300 s.
Step 6: Calculate the power. 1500 J divided by 300 s equals 5 W.
Step 7: Conclude that the average power output of the cyclist is 5 watts.

Power Calculation – Power is defined as the rate at which work is done, calculated by dividing the total work done by the time taken.
Unit Conversion – Understanding the need to convert time from minutes to seconds for accurate calculations.
