The diagram shows the forces acting on a cyclist as she accelerates at 4.0 m s–2
on a straight, horizontal section of road. The constant resistive forces are air resistance and a 300 N force due to friction.

[see diagram below]

The combined mass of the cyclist and bicycle is 50 kg.
What is the value of the air resistance?

A. 50N
B. 100N
C. 200N
D. 300N
E. 450N

First make sure to draw the forces on paper. This way you can see that the solution is simply given via the equation F=m*a since we know all the forces but one, the mass and the acceleration.
