find the second derivative of the position. And plug in 1 for t to solve for acceleration at 1sec.

velocity is the first derivative.

acceleration is the second derivative.

would it be –52 cm/sec2 –40 cm/sec2 –24 cm/sec2 –12 cm/sec2 There are four answers and I'm not sure which one it is. If I find out the answer I can work backward to figure out how to solve it.
