1. The problem statement, all variables and given/known data A car is traveling at 27.8 m/s, it undergoes a negative acceleration of 2.6 m/s/s when the brakes are applied. How many revolutions will the tires go through before the car comes to a stop if the wheels each have a radius of 1.0 m? 2. Relevant equations α = at / r -> angular acceleration = tangential acceleration / radius α = ω / t -> angular acceleration = angular velocity / time α = Θ / t^2 -> angular acceleration = angle / time^2 ω = Θ / t -> angular velocity = angle / time ω = v / r -> angular velocity = velocity / radius 3. The attempt at a solution ω = v / r ω = 27.8 / 1 ω = 27.8 α = a / r α = (- 2.6) / 1 α = -2.6 α = ω / t -2.6 = 27.8 / t 27.8 / 2.6 = t 10.7sec = t ω = Θ / t 27.8 = Θ / 10.7 Θ = 297.46° 297.46 / 360 = 0.83 times This was incorrect.
