Question statement

A train travelling at $\var{u_A}\,\mathrm{ms^{-1}}$ passes point A and starts to accelerate with constant acceleration.

$\var{t_1}\,$ seconds later, its speed is $\var{v1}\,\mathrm{ms^{-1}}$

Find

(a) the acceleration of the train

(b) the distance the train travels while accelerating (in metres)

The train continues to travel at a constant speed. The driver then applies the brakes, bringing the train to a stop at point B with a constant deceleration of $\var{alpha}\,\mathrm{ms^{-2}}$

(c) if the total distance travelled by the train from A to B is $\var{s_AB}\,$ km, find the total time taken by the train to cover this distance

Give any introductory information the student needs.
