# Homework Help: Rocket Acceleration, position and velocity

1. Sep 23, 2007

1. The problem statement, all variables and given/known data

"The acceleration of a certain rocket is given by a=Ct, where C is a constant. (a) Find the general position function x(t). (B) Find the position and velocity at t=5 s if x= 0 and v= 0 at t=0 and C= 3 m/s^3"

so

a= Ct

t=5s
x=0

v=0
t=0
C= 3 m/s^3

2. Relevant equations

3. The attempt at a solution
(a) Ill assume a "general position function" is just a small sketch of an "x vs t" Graph, since the rocket is accelerating the graph should just be a, concave curve up.

(B)I have no clue what exactly the question is asking for, with the given data.

velocity is the integral of acceleration. position is the integral of velocity. Use that for the first part.
