3. The tire of a car has a radius of 0.26m. As the car travels down the street, the wheel spins with an angular velocity of w-80rad/s. a. How many times does the wheel spin per second? second? per b. How fast is a point on the edge of the tire moving, in meters (Incidentally, this is equal to the speed of the car as it drives down the road.)
Angular speed, acceleration and displacement
Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.
Angular Position
Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.
Given data:
Radius (r) = 0.26 m
Angular velocity (ω) = 80 rad/s
Required:
The frequency (f) and linear speed (v) of a point on the edge of the tire
