Question

An electric car is subjected to acceleration tests along a straight and level test track. The resulting v-t data are closely modeled over the first 10 seconds by the function v = 24t - t² +5t^1/2, where t is the time in seconds and v is the velocity in feet per second. Determine the displacement s as a function of time over the interval 0 ≤ t ≤ 10 sec and specify its value at the indicated times.
