Question

How much torque is applied to a bicycle wheel whose radius is 0.40 m in order to accelerate the 15 kg bike and 78 kg rider at a rate of 3.4 m/s^2?

I'm totally lost on this one. Which equation do I need to use?

Ignore the moment of inertia of the wheel.

F=ma solve for F

Now that F must come from the wheel-ground connection, and Torque/radius=forceatground

Torque=ma/r
