    Distance traveled with acceleration & deceleration

    Interesting. Let me give it a go. X = V1avg * t1 + V2avg * t2 X = 0.5 * a1t1 * t1 + 0.5 * a2t2 * t2 X = (0.5 * -9.8 * 3) * 3+ (0.5 * 5.88 * 5) * 5 X = -44.1 + 73.5 similar numbers as the first way, but a different sign... Certainly something else to consider! Thanks!

    Distance traveled with acceleration & deceleration

    Hmmm... The only formula I know for average velocity is: Avg Velocity = Distance/Time. Distance is unknown and Avg Velocity is unknown. Is there another equation for avg velocity that I'm not aware of?

    Distance traveled with acceleration & deceleration

    I'm glad to hear I'm not too far off on the methodology. I'm going to stick with -ve for gravity. Yes, I believe that the deceleration is intended to be constant.
