You and your bicycle have combined mass 80.0 kg. When you reach the base of a bridge, you are traveling along the road at 4.50m/s (the figure (Figure 1) ). At the top of the bridge, you have climbed a vertical distance of 5.20 m and have slowed to 2.50m/s . You can ignore work done by friction and any inefficiency in the bike or your legs.
