The wheel of a car has a radius of 0.288m and is being rotated at 830 revolutions perminute on a tire-blanacing machine. a)Determine the speed at which the outer edge of the wheel is moving.
b)Determine the centripetal acceleration at which the outer edge of the wheel is moving.

• Physics -

a) V = R w
w is the angular speed in radians/sec

Convert rpm to radians per sec before using that formula

b) a = R w^2
