Extracted text: 4. A particle travels along a straight line with a constant acceleration. When s = 4 ft, v 3 ft/s and when s 10 ft, v = 8 ft/s. Determine the velocity as a function of position. (V9.17s – 27.7) ft/s Ans. 5. The velocity of a particle traveling in a straight line is given by v= (6t - 31) m/s, where t is in seconds.
