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.
Part A:
What is the total work done on you and your bicycle when you go from the base to the top of the bridge?
This was Part B
How much work have you done with the force you apply to the pedals?
Which I found the correct answer which was 3520 J.
