given the acceleration
Ax=6t^2
Ay=-0.66PI*cos(0.66PI*t)
and knowing that the starting point was (0,0) and that the starting velocity was V0=(-1,0)
find the Velocity vector and the placement vector
si what i did was- 1st integral on Ax Ay getting
Vx= 2t^3-1
Vy=-sin(0.666PI*t)
which is fine and is true to the facts- V0=(-1,0)
but then, 2nd intergal, integral in Vx, Vy
and
Rx= 0.5t^4-t
which is fine, X0=0
BUT
Ry= 1.5PI*cos(0.66PI*t)
and then Y0 is not 0, i have checked and double checked and triple checked and cannot find my fault, any ideas?/
