Question
A train of mass 200 tonne travelling at 140 km/hour applies the brakes fiercely, so
that the brakes lock and the wheels slide along the rails. It stops after sliding
1000m.
Calculate:
(i) The acceleration,
(ii) The longitudinal force on the rails,
(iii) The coefficient of friction between the rails and the wheels
