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 +5+¹/2, where it is the time in seconds and vis the velocity in feet per second. Determine the displacements as a function of time over the interval Osts 10 sec and specify its value at the indicated times. 160 140
