Quantify the power output that is required to clean a 115.0 kg barbell through a distance of 0.90 meters in 0.55 seconds. Calculate the work that is accomplished in cleaning a 125.0 kg barbell through a distance of 0.95 meters in 0.60 seconds. Which of the two, aforementioned (i.e., question #7 and question #8) scenarios involve the greater power output?

Step 1
Work is calculated as the product of force and distance. In this case, the force is equal to the weight of the barbell (mass times gravity). For the 115.0 kg barbell: Force = mass * gravity = 115.0 kg * 9.81 m/s^2 = 1127.15 N Work = force * distance = 1127.15 N * Show more…
