Question

Compare the forward force on the bike with the backward force on the bike when Megan was travelling at a constant speed. plsssss help!

Answer 1

Explanation:

the forward force is the force that Megan applies to the pedal to go forward - the backward force is due to the air resistance and the friction between the wheels and the track In this case, Megan is travelling at constant speed. This means that her acceleration is zero: a = 0 According to Newton's second law, the resultant of the forces acting on Megan is equal to the product between mass (m) and acceleration (a): However, a = 0, so the resultant of the forces is also zero: and this implies that the forward force and the backward force are equal in magnitude and opposite in direction.
