    Rocket Acceleration, position and velocity

    Homework Statement "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...
