Suppose a car has a 100 000-mile 10-year warranty on its wheels and axles. How may turns will the wheels of 0.70-m diameter make if both the mileage and time warranties run out simultaneously and what will be the average angular velocities of the wheel? Assume that a mile = 1.6 × 10^3 m and that a year is 3.16 × 10^7 s
a. 7.3E+7, 14 rad/s b. 2.3E+8, 1.4 rad/s
c. 3.5E+8, 1.4 rad/s d. 7.3E+7, 1.4 rad/s
e. 2.3E+8, 14 rad/s
