A bus moves in a straight line between two bus stops. The bus starts from rest and accelerates at 2.1 \(\text{m/s}^2\) for 5 s. The bus then travels for 24 s at constant speed and finally slows down, with a constant deceleration, stopping in a further 6 s. Sketch a velocity-time graph for the motion and hence find the distance between the two bus stops.
