A car starts from rest, moving along a straight line, first with an acceleration a = 5m/s^2 starting from rest, then uniformly and finally decelerating at the same rate 5m/s^2, comes to rest. If the total time of motion of car is 25 s and average velocity during the time is equal to v = 20 m/s . How long does the particle move uniformly? Need step-by-step explanation. No spam. Thanks.
