A model rocket is launched straight upward with an initial speed of 70.0 m/s. It accelerates with a constant upward acceleration of 1.00 m/s2 until its engines stop at an altitude of 190 m. (a) What is the maximum height reached by the rocket? m I don't know what I am doing wrong here. I have two pages full of screw ups, haha. I tried to find out the final velocity it hits right before it runs out of fuel and I'm stuck Using: [tex]x = x_0 + v_0 t + (1/2) a t^2[/tex] I did 190 = 0 + (70)t + 1/2(1)(t^2) I get down to 190 = 70t + .5t^2 I'm just lost so just some guidance would be nice, I know the steps I'm just making a simple error somewhere or something and I've tried for like 60 minutes, so I figured I'd post.
