Another projectile motion?

Since it asks what is the speed of the car just before it lands you are looking for Vfinal. You have delta X. and acceleration is gravity which is 9.8 m/s^2. So you can use the constant acceleration equation: Vfinal^2= Vinitial^2+ 2a(x-xinitial). So I solved for Vfinal and got 37.4 m/s. You may want to check my math though.
