Problem 7: During a very quick stop, a car decelerates at 7.6 m/s. Assume the forward motion of the car corresponds to a positive direction for the rotation of the tires (and that they do not slip on the pavement). Randomized Variables a, = 7.6 m/s2 r = 0.255 m wo = 91 rad/sPart (a) What is the angular acceleration of its tires in rad/s, assuming they have a radius of 0.255 m and do not slip on the pavement? Numeric : A numeric value is expected and not an expression. Part (b) How many revolutions do the tires make before coming to rest, given their initial angular velocity is 91 rad/s ? Numeric : A numeric value is expected and not an expression. N = Part (c) How long does the car take to stop completely in seconds? Numeric : A numeric value is expected and not an expression. Part (d) What distance does the car travel in this time in meters? Numeric : A numeric value is expected and not an expression. X= Part (e) What was the car's initial speed in m/s? Numeric : A numeric value is expected and not an expression
