4 A car is driven with constant acceleration, \(a \mathrm {~m} \mathrm {~s} { } ^ { 2 }\), along a straight road. Its speed when it passes a road sign is \(u \mathrm {~ms} { } ^ { 1 }\). The car travels 14 m in the 2 seconds after passing the sign; 5 seconds after passing the sign it has a speed of \(19 \mathrm {~ms} { } ^ { 1 }\).

1. Write down two equations connecting \(a\) and \(u\). Hence find the values of \(a\) and \(u\).
2. What distance does the car travel in the 5 seconds after passing the road sign?
