Suppose a car has a 100,000 mile 10 year warranty on the wheels and axles of a car. How may turns will the wheels of 0.80-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 = m and that a year is s.

Car A is traveling at 22.0 m/s and car B at 29.0 m/s. Car A is 300 m behind car B when the driver of car A accelerates his car with a uniform forward acceleration of 2.40 m/

How long after car A begins to accelerate does it take car A to overtake car B? A) 5.50 s B) 12.6 s C) 19.0 s D) 316 s E) Car A never overtakes car B.
