1. The equation of motion is given by s=sin2πt (m) . Find the acceleration after 4.5 seconds
Im getting confused on whether the above equation is for velocity or distance.
I know the derivative of distance is velocity and that the derivative of velocity is acceleration.
If i take the derivative of the above equation i end up with
Sa=cos 2π
This eliminates T , So I am not sure what I am doing wrong.
Thanks in advance for help.
Cheers
