1. The problem statement, all variables and given/known data A car passes through traffic lights as they turn from red to green at a speed of 12ms-1. A motorcyclist, starting from rest, accelerates from the traffic lights in the same direction as the car at 1.5ms-2. After what distance from the lights will they meet? (OPTIONS: 16m, 120m, 168m, 192m). 2. Relevant equations 3. The attempt at a solution 12t = d, and 1.5t2 = d. 12t = 1.5t2. 1.5t2 - 12t = 0. t(1.5t -12) = 0. t = 0 or 8. 12ms-1 * 8s = 96m. Not an option.
