Calculating Projectile Speed for Takeoff & Landing Ramps

[Applesauce2]

Hi, I've been trying to figure this out for a few hours...can't seem to get it. Any help is greatly appreciated

Homework Statement

I have two ramps (a takeoff and a landing ramp). I know the angle and height of both. I also know the distance in between the ramps. I am trying to find the minimum speed required to clear the gap.

I'm just trying to find a formula so I don't have specific numbers.

Homework Equations

the kinematic equations?

The Attempt at a Solution

I've been trying to use the kinematic equations to solve this. I don't really have anything to show my work. I'm pretty stumped. I've just kind of been trying random stuff hoping some unknown variable will cancel out or something


Thanks in advance for any help

Well, you know the initial trajectory (based on the launch-ramp angle), and you know the distance it has to travel... just like a cannon problem, you can solve.
(Don't forget to take into account any difference in height between the two ramps)

Hey, I've been really busy so I haven't had much time to work on this. Could I possibly get another hint . I can't seem to figure it out.
