## Homework Statement

"In a movie scene involving a car chase, a car goes over the top of ramp A and lands a B below. Determine the speed of the car at A if the car is to cover distance d=180ft for [itex]\alpha[/itex] =15° and [itex]\beta[/itex] = 30°. Neglect aerodynamic effects.

## Homework Equations

Word.doc is the problem picture.

## The Attempt at a Solution

I have calculated the distance the car moves the in X, and falls in the Y. But other than that I am rather lost mathematically.

The hint for the problem states: "The required initial speed can be found from the intersection of the parabolic trajectory and the straight line whose slope in determined by tanβ"

Only problem is I have no idea as to what line tanβ is the slope of.
