It Icav es? 37, Dragsters can actually reach a top speed of 145 m/s in only 4.45 s- 0 and Example 2.11. (a) Calculate the average acceleration for such a dragster. (b) Find the final velocity of tis dragster starting from rest and accelerating at the rate found in (a) for 402 m (a quarter mile) without using any information on time. (c) Why is the final velocity greater than that used to find the average acceleration? Hint: Consider whether the assumption of constant acceleration is valid for a dragster. If not, discuss whether the acceleration would be greater at the beginning or end of the run and what effect that would have on the final velocity. considerably less time than given in Example
