A car initially traveling at $27\mathrm{.}2$ m$/$s undergoes a constant negative acceleration of magnitude $1\mathrm{.}70$ m$/$s$^2$ after its brakes are applied. How many revolutions does each tire make before the car comes to a stop, assuming the car does not skid and the tires have radii of $\mathrm{.}310$ m$?$ What is the angular speed of the wheels when the car has traveled half the total distance
