1 A cyclist is riding a bicycle along a straight horizontal road \(A B\) of length 50 m . The cyclist starts from rest at \(A\) and reaches a speed of \(6 \mathrm {~ms} ^ { - 1 }\) at \(B\). The cyclist produces a constant driving force of magnitude 100 N . There is a resistance force, and the work done against the resistance force from \(A\) to \(B\) is 3560 J . Find the total mass of the cyclist and bicycle.
