A car initially traveling at 33.6 m/s undergoes a constant negative acceleration of magnitude 1.70 m/s2 after its brakes are applied.
What is the angular speed of the wheels when the car has traveled half the total distance?

-
The angular speed of the wheels cannot be known without knowing the wheel radius.
Dtot = V²/2a = 332 m
½Dtot = d = 166 m
v = √[Vi² - 2ad] = 23.76 m/s
w = v/r = 23.76/r rad/sec where r is the radius of the wheel
