## Homework Statement

A toy rocket, launched from the ground, rises

vertically with an acceleration of 23 m/s2 for

11 s until its motor stops.

Disregarding any air resistance, what max-

imum height above the ground will the rocket

achieve? The acceleration of gravity is

9.8 m/s2 .

Answer in units of km.

## Homework Equations

I used kinematics equation: x=Vo*t + 1/2at^2

## The Attempt at a Solution

I was a little unsure how to go about this problem, since most free fall problems I've dealt with use only gravity as acceleration.

I tried plugging the following values into my equation:

Vo = 0m/s

a = 23 m/s^2

t = 11s

I got the answer 1391.5m, but this was wrong. I think the problem is simpler than I'm thinking about it, but I can really use some help on this.
