MATH 1241 Test Review -Module 2 Sec 2.3 - 2.8 9 A particle moves on a Horizontal line so that its coordinate (distance) at time t is s(t) = -+3 + 30t' - 225t with t 2 0. i. Find the velocity (in ft/sec) of the particle at time t = 4. ii. Find the acceleration (in ft/sec?) of the particle at time t = 4. The particle stops moving twice, once when t = A and again when t = B. (Where A
