A small metal particle passes downward through a fluid medium while being subjected to the attraction of a magnetic field such that its position is observed to be = (15 - 3) mm, where is measured in seconds. Determine (a) the particle's displacement from = 2 s to = 4 s, and (b) the velocity and acceleration of the particle when = 5 s.

• A. s = 834 mm, v = 1122 mm/s, a = 450 mm/s
• B. s = 114 mm, v = 1122 mm/s, a = 450 mm/s
• C. s = 114 mm, v = 450 mm/s, a = 1122 mm/s
• D. s = 834 mm, v = 450 mm/s, a = 1122 mm/s
