SITUATION 5: The mass of you riding a bicycle is equal to 80kg. When you reach the base of a bridge, you are traveling at 5m/s. At the top of the bridge. you have climbed a vertical distance of 5.20m and have slowed to 1.50m/s. Ignoring friction between the tires and the road, and efficiency is neglected. a. What was the total work done when you reached the top of the bridge? b. Determine how much work you have done with the force you apply to the pedals?.
