What is the angular speed of the wheels when the car has traveled half the total distance

v = √[Vi² - 2ad] = 23.w = v/r = 23.......
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
