I need verification that the answers are correct/incorrect

The position of a car as a function of time t, with t> 0 and expressed in seconds, is 7 (t) = ((5.98t² + 0.139t³ – 0.0149t¹) i + (0.523t² +0.0122t³ -0.00131t¹))) ft. Determine the velocity, and speed, and acceleration of the car for t= 15.5 s. (Round the final answers to four decimal places. Include a minus sign if necessary) 10 The expression of the velocity of the car is v (15.5 s) = ( 63.62 The speed of the car is 63.86 ft/s. The expression of the acceleration of the car is à (15.5 s) - -18.07 5.493 ) ft/s. -1.596) ft/s²
