Q1. A vehicle travels around a bend on a banked track at a constant speed of 25 m/s and at an effective radius of 100 m. The vehicle has a wheel base width of 1.6 metres and a centre of gravity 1.4 metres above the track surface. Calculate EACH of the following:

(a) The minimum angle of banking required to prevent the vehicle from overturning;

(b) The minimum coefficient of friction between the track and the vehicle to prevent the vehicle sliding when the track is banked at the angle calculated in Q5(a).
