In physics, if a moving object has a starting position at s 0, an initial velocity of v 0, and a constant acceleration a, then the position s at any time t > 0 is given by: s = 1/2at 2 + v 0 t + s 0. solve for the acceleration, a, in terms of the other variables. for this assessment item, you can use ^ to show exponents and type your answer in the answer box, or you may choose to write your answer on paper and upload it.
