Suppose a wheel is rolling down the street with a linear speed of 20.0 m/sec. What is the magnitue of the angular speed of the wheel if it has a radius of 25
cm? Give your answer in rad/sec

Identify the forces that contribute to the centripetal force on the object in each of the following examples: a. a bicyclist moving around a flat, circular track b. a bicycle moving around a flat, circular track c. a racecar turning a corner on a steeply banked curve

However, had it been a real sound, the sound's pitch would have been increased by the doppler effect, since the falcon was moving the source of the sound. perpendicular to away from towards at the same speed as
