Jane is 71 kg (~156 lb) and her bike has a total mass of 9 kg.She plans on riding a new canyon road that starts at an elevationof 5,400 ft and ends 13 miles up the winding and protected canyon(i.e. minimal winds) at an elevation of 8,000 ft. This ride usuallytakes over an hour to complete. Since you now know that mechanicalwork is calculated as the force times the displacement, describehow you would go about calculating the total mechanical work doneagainst gravity for this bike ride.
