An electric car undergoing performance testing is travelling at an initial velocity of 14 m s-1 and accelerates at a constant rate of 3.2 m s-2 along a straight horizontal track of length 90 m.
What is the final velocity of the car at the end of the track?
22.0 m s−122.0\text{ m s}^{-1}22.0 m s−1
24.0 m s−124.0\text{ m s}^{-1}24.0 m s−1
27.8 m s−127.8\text{ m s}^{-1}27.8 m s−1
38.0 m s−138.0\text{ m s}^{-1}38.0 m s−1
