A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...

A bicycle wheel has a diameter of 64.0 cm and a mass of 1.76 kg. Assume that the wheel is a hoop with all of the mass concentrated on the outside radius. The bicycle is placed on a stationary stand and a resistive force of 119 N is applied tangent to the rim of the tire. (a) What force must be applied by a chain passing over a 8.99 cm diameter sprocket if the wheel is to attain an acceleration...
