Question

Starting from rest at time t=0 a car moves in a straight line with an acceleration plotted on an accleration vs time graph as follows:

t=0 a = 5 m/s²
t=1 a= 4 m/s²
t=2 a = 3 m/s²
t=3 a = 2 m/s²

What is the speed of the car at t=3 s? Please show work. Please use kinematic equations or algebra to solve.
