A truck traveling east has a velocity of 26 m/s. (a) Calculate its velocity after accelerating at 1 m/s2. (b) The truck then decelerates at -2 m/s2 for 3 s. Now what is its velocity? (c) The truck then takes 8s to change its velocity to 21 m/s. What was its final acceleration?
I tried using 1s (a), and I got 27 m/s. Using 27 m/s in (b), I got 21 m/s. But then for (c) the velocity is also 21, so it doesn't make any sense. Help?
