At takeoff, a commercial jet has a speed of 62 m/s. Its tires have a diameter of 0.86 m. a) At how many rev/min are the tires rotating? b) What is the centripetal acceleration at the edge of the tire in m/s^2? c) With what force must be determined 0.75x10^-15 kg bacterium cling to the rim in N? d)Take the ration of this force to the bacterium's weight.
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.
