1. A car undergoes non-constant acceleration from an initial speed of 4.00 m/s in the reverse direction to a final speed of 8.00 m/s in the forward direction. If this trip lasts 24.0 s and if the car moves 30.0 m in the reverse direction during this trip, a. what are the magnitude and the direction of the car's average velocity, and VO= - 4.00 m/s AX V = 8.00 m /s t= 24.0s X = 30.0 m
