1. The problem statement, all variables and given/known data
A model rocket is launched from rest with an upward acceleration of 6.00m/s^2 and, due to a strong wind, a horizontal acceleration of 1.50m/s^2. How far is the rocket from the launch pad 6.00s later when the rocket engine runs out of fuel? 2. Relevant equations Not sure.. 3. The attempt at a solution I've been trying to figure this out, and I'm still not sure how to approach it.

Sketch a velocity vs. time graph.
You will see that from zero the velocity increases with the rate 6(m/s)/s for 6 secs. Then it slows down to with rate of g untl zero velocity where it is at the top of the flight Next it will continue with negative velocity(acceleration g) until it reaches the ground. The net total area is equal to zero. The horizontal vector remains constant. Taking total flight time, you can multiply this to horizontal velocity to find the answer.
