Q) The position of a particle traveling along a straight line is s(t) = (t- 3t +C) ft, where t is in seconds and C is a constant. If s = 4 ft when t = 0, determine the velocity of the particle when t = 4 s. What is the total distance traveled during the time interval t = 0 to t = 4 s? Also, %3D %3D %3D what is the acceleration when t = 2 s?
