The position of a particle in millimeters is given by s = 119 - 24t + t2 where t is in seconds. Plot the s-t and v-t relationships for the first 17 seconds. Determine the net displacement Δs during that interval and the total distance D traveled. By inspection of the s-t relationship, what conclusion can you reach regarding the acceleration? Answers:

Δs = mm
D = mm
