Kinematics question
I would like a *hint* to this problem  perhaps the first unknown to solve for.
During training, an aerial skier takes off from a ramp that is inclined at 40.0 degrees to the horizontal and lands in a pool that is 10.0 m below the end of the ramp. If she takes 1.50 s to reach the highest point of her trajectory, calculate:
a. the speed at which she leaves the ramp
I've drawn a right angled triangle. I'm stuck because there is no initial velocity, no height and no displacement given. What should I first try for?
TIA,
