-(5a)/(5) = (48)/(5) a = 9.6ms^-2 Example 4 A body accelerates uniformly from rest at the rate of 3ms^-2 for 8s. Calculate the distance covered by the body during acceleration. WAEC 1992 Solution Using appropriate symbols deduce, the known and unknown from the question. Acceleration, a = 3m/s^2; initial velocity, u = 0; time, t = 8s; distance, s = ? Therefore the most appropriate equation that includes a, u, t and s is the second equation of motion: s = ut + (1)/(2)at^2 Substituting: s = 0 × 8 + (1)/(2) × 3 × 8^2 = 0 + (1)/(2) × 3 × 64 = 96m Example 5 Starting from rest, a Formular One car accelerates uniformly at 25m/s^2 for 30s. What distance does it cover in the (i) last one second of motion. (ii) seventeenth second of motion. Solution The distance in the last one second of motion is the distance it covered between time interval of the 29^th and 30^th second. It is calculated by subtracting the distance in the 29^th sec from that of the 30^th sec. Distance, s = S_30 - S_29 But, S_30 = ut + (1)/(2)at_30^2 and S_29 = ut + (1)/(2)at_29^2 Starting from rest, initial velocity, u = 0. Therefore, ut = 0 in each case s = (1)/(2)at_30^2 - (1)/(2)at_29^2 = (1)/(2)a(t_30^2 - t_29^2) From the question, acceleration, a = 25m/s^2; t_30 = 30s; t_29 = 29s. So substituting into above equation: s = (1)/(2) × 25(30^2 - 29^2) = 12.5 (900 - 841) = 12.5 (59) = 737.50m. (ii) From question acceleration, a = 25m/s^2; initial velocity, u = 0; time, t is not equal to 17s because the 17^th second is actually the time interval between the 16^th and 17^th second, therefore time, t = t_17 - t_16. Substituting into s = (1)/(2)a(t_2^2 - t_1^2) s = (1)/(2) × 25(17^2 - 16^2) = 12.5 (289 - 256) = 12.5 × 33 = 412.5m. Note: In
