Question

what is the work done (ft lb) by someone on a bicycle who goes from rest to 38mph? The total weight of the person and the bicycle is 200lb.

Answer 1

The work done by someone on a bicycle from rest to 38 mph is 11,172 ft lb.

Step-by-step explanation:

The work done by someone on a bicycle can be calculated using the equation: Work = Force x Distance. In this case, the force is the weight of the person and the bicycle, which is 200 lb, and the distance is the distance traveled from rest to 38 mph. To calculate the distance, we need to convert the speed from mph to feet per second. 1 mph is equal to 1.47 ft/s, so 38 mph is equal to 38 x 1.47 = 55.86 ft/s.

Now we can calculate the work done: Work = Force x Distance = 200 lb x 55.86 ft/s = 11,172 ft lb. Therefore, the work done by someone on a bicycle from rest to 38 mph is 11,172 ft lb.
