Fug I can't remember physics lessons at all

Use Kinematic equations for the x direction. Since u have a constant velocity

I dunno, I'm bad at physics :(

The equation for this would be "v_final^2 = v_initial^2 + 2*a*d". I forget how you derive this, but it follows from the others IIRC, so just consider it known a priori. Anyway, you need to use this twice: once with a final v of 0 and a distance of 34 to figure out your starting velocity, and then use that as the initial velocity with a distance of 17.

>kinematic equations
holy shit that takes me back.

Just remeber that acceleration is a second derivative of speed! That d = v*t + 0.5*a*t^2!

It's 1. 10.9m/s
v0 is 15.43m/s.

Some decimals are (,) - fuck yeah, Europe!

Using >>5636321's formula:
Full distance to calculated initial speed, v0:
0^2 = v0^2 + 2 * (-3.5) * 34
v0^2 = 238 [m^2/s^2]

Let's use this in the same formula for 17m distance:
v1^2 = 238 + 2 * (-3.5) * 17
v1 = sqrt(238 - 119) = 10.9

Amirite?
