At=7.4 m/s^2
R=0.29 m
W0=99 rad/s
Part: what is the angular acceleration of its tires in Rad/s ^2
assuming they have a radius of 0.2 9 AM and do not slept on the pavement
Part b: how many revolution do the tires make before coming to a rest given their initial angler velocity is 99 RAD/S
Part :c how long does the car take to stop completely in seconds
Part d what distance does the car travel in this time in meters
Part e what was the car initial speed in M/S
Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
