Question 114

A car passes three posts P, Q and R, on a straight horizontal road. The distance PQ=50mPQ = 50\text{m}PQ=50m. The distance QR=100mQR = 100\text{m}QR=100m. The car, moving with constant acceleration, takes 2 seconds to travel from P to Q and 3 seconds to travel from Q to R.

a.

Verify that the acceleration of the car is 103 ms−2\displaystyle \frac{10}{3} \text{ ms}^{-2}310​ ms−2

[3]
b.

Verify that 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
