A mustang going from 0 to 60 in 3.5 seconds has an acceleration of 7.7m/s. Radius of the tires is .35m, what is the angular displacement of the tires between the rest time and 60mph. Provide answer in radians and use the revolution of a tire is 2 x pie x r to convert to the linear distance that was traveled. Then also confirm this by using kinematics.
