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 5.00 m>s
(Fig. ). At the top of the bridge, you have climbed a vertical distance
of 5.20 m and slowed to 1.50 m/s. Ignore work done by friction and any
inefficiency in the bike or your legs. (a) What is the total work done on
you and your bicycle when you go from the base to the top of the bridge?
(b) How much work have you done with the force you apply to the pedals?
