A particle travels along a straight line with a velocity v = (1-2)(-3t+2) m/s, where r is in seconds [or v=-5 +81-4]. Initially the particle is located 4 m to the left of the origin O. 1) Find the acceleration when t = 2s. Is the particle decelerating at that time? Why? Does the particle change its initial direction of motion? Explain. Determine the total distance traveled by the particle in t = 6 s. 0 S
