A powerful motorcycle can produce an acceleration of 3.50
Chapter 4, Problem 10(choose chapter or problem)
Problem 10PE
A powerful motorcycle can produce an acceleration of 3.50 m/s2 while traveling at 90.0 km/h. At that speed the forces resisting motion, including friction and air resistance, total 400 N. (Air resistance is analogous to air friction. It always opposes the motion of an object.) What is the magnitude of the force the motorcycle exerts backward on the ground to produce its acceleration if the mass of the motorcycle with rider is 245 kg?

ANSWER:
Step 1 of 3:
The acceleration of the motorcycle is given. The forces opposing the motion of the motorcycle are air resistance and friction. The total frictional force is also provided. We are going to calculate the backward force exerted on the ground to produce acceleration by the motorcycle.
The mass of the motorcycle with the rider
The acceleration produced
The total frictional force
