Question

6. Two physics students, Will N Andable and Ben Pumpiniron, are in the weightlifting room. Will lifts the 100-pound barbell over his head 10 times in one minute; Ben lifts the 100 -pound barbell over his head 10 times in 10 seconds.Which student does the most work? Which student delivers the most power? Explain your answers.

Answer 1

Both students do the same amount of work. Ben delivers the most power.

Answer 2

## Step 1In physics, work is defined as the force applied to an object times the distance the object is moved. In this case, both Will and Ben are lifting the same weight (100 pounds) the same distance (over their heads 10 times). Therefore, they both do the same amount of work, which is 1000 pounds.## Step 2Power, on the other hand, is defined as work done per unit time. In this case, Will lifts the barbell 10 times in one minute, which is equivalent to 10 times in 60 seconds. This means he does 1 work every 6 seconds. ## Step 3Ben, on the other hand, lifts the barbell 10 times in 10 seconds. This means he does 1 work every 1 second. ## Step 4Since power is work done per unit time, Ben does more work per second, which means he delivers more power.
