The position of a particle in millimeters is given by s = 84 - 19t+t2 where t is in seconds. Plot the s-t and v-t relationships for the first 12 seconds. Determine the net displacement As 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: As = mm D= mm I i
