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!

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?

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.
