You and your bicycle have combined mass 80.0 kg. When you reach the base of a bridge, you are travelling along the road at 7.50 m/s. At the top of the bridge, you have climbed a vertical distance of 5.20 m and have slowed to 3.00 m/s. You can ignore work done by friction and any inefficiency in the bike or your legs. Part AWhat is the total work done on you and your bicycle when you go from the base to the top of the bridge?Part BHow much work have you done with the force you apply to the pedals?
