Solve the below:
Q: A car starts moving rectilinearly, first with acceleration w = 5.0 m/s2 (the initial velocity is equal to zero), then uniformly, and finally, decelerating at the same rate w, comes to a stop. The total time of motion equals t 25 s. The average velocity during that time is equal to (v) = 72 km per hour. How long does the car move uniformly?
