Question 106

A car passes three posts P, Q and R, on a straight horizontal road. The car, moving with constant acceleration, takes 2 seconds to travel from P to Q and 3 seconds to travel from Q to R. The acceleration of the car is 103 ms−2\displaystyle \frac{10}{3}\text{ ms}^{-2}310​ ms−2. The speed of the car at the instant it passes Q is 853 ms−1\displaystyle \frac{85}{3}\text{ ms}^{-1}385​ ms−1.
