A boy is riding his bike from his house to the
corner store. The force of his pedaling forward is 60 N. The air friction
pulling against him has a force of -5 N, and the rolling friction working
against his tires is -2 N. If the boy and his bike's mass together is 83 kg,
what is his acceleration?

Answer - 0.64 m/s^2

A = Force/ Mass

F = 60 - 5 - 2 = 53

A = 53 / 83

A = 0.64 m/s^2
