ANGULAR SPEED OF A RACE CAR. A race car is driven around a circular track at a constant speed of 180miles per hour. If the diameter of the track is 1/2mile, what is the angular speed of the car? Express your answer in revolutions per hour(which is equivalent to laps per hour)
Please show me the steps to solving this.
Thanks.
speed is distance/time
how far is one lap? 1 revolution
What is the time for one lap? time= distance/speedgiven.
what is the angular speed? revolution/time
check the units to make certain angular speed is in revs/hr.
