V2-V1 = V --> V/A = time --> m/s × s^2/m = seconds
(24-0)m/s ÷ 2m/s^2 = 24m/s × s^2/2m
= 12 seconds --> time from start to top speed
(V2-V1)/A = (0-24)m/s^2 ÷ -1.2m/s^2
= -24m/s × s^2/-1.2m = 20 seconds
--> time from top speed to stopping
So total time is 12+20 = 32 seconds
D(m) = V1T + 1/2A(m/s^2) × T^2(s^2), where V1 (initial speed) = 0, so V1T=0
D1 = 1/2×2m/s^2 × 12^2s^2 = 1×144m
= 144m --> first distance from start to top speed (24)
D2 = V1T + 1/2×AT^2, where V1 = 24
D2 = 24(20) + 1/2×1.2m/s^2 × 20^2s^2 = 480m + 0.6×400m = 480+240 = 720m --> time from top speed (24) to stopping
So the total time = 32 seconds and the total distance traveled = 144+720 = 864 meters
