An object moving with constant acceleration has velocity v = 71.5 meter per second when it is at x = 6.9 meter and v = 143.2 meter per second when it is at x = 13.4 meter. Determine what is its acceleration? Determine how much time does it take for the particle to accelerate from 71.5 m/s to 143.2 m/s? Determine how fast will the particle be moving when it is located at x = 25.5 m?
