Question

A particle moves along the x-axis so that at any time t, measured in seconds, its position is given by s(t) = sin(t) − 4cos(2t), measured in feet. What is the acceleration of the particle at time t = π seconds?

Answer 1

Take the derivative two times to get acceleration, and then plug in \[\pi\]. First derivative gives you velocity, and derivative of velocity gives you acceleration

Answer 2

Ok so what do i get as the answer

Answer 3

what did you get for s''(t) ?
