The cyclist has a mass of 50 kg and is accelerating at 0.9 m/s^2.what is the size of the unbalanced force f acting on the cyclist?

Unbalanced force = F = 45 N

Explanation:

According to the Newton's second law of motion Acceleration of an object is directly proportional to the net force or unbalanced force acting on it. Its mean that When there is some unbalanced force acting on an object, there must be an acceleration.

Given data:

Mass = m = 50 kg

Acceleration = a = 0.9 m/s²

Unbalanced force = F = ?

According to the Newton's second law of motion

                                  F = ma

                                  F = (50)(0.9)

                                  F = 45 N
