A bicycle wheel has a diameter of 64.6 cm and a mass of 1.70 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 120 N is applied tangent to the rim of the tire. a) What force must be applied by a chain passing over a 9.07 cm diameter sprocket if the wheel is to attain an acceleration of 4.53 rad/s^2 ?
b) What force is required if the chain shifts to a 5.51 cm diameter sprocket?

19 hertz bruh u trippin? ?

Sorry i don’t know what to do

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
