Figure Q1 shows a train accelerates with constant acceleration on a straight length of track from Om/s to a maximum velocity. Then it travels on a bend at this constant (maximum) velocity. On the straight track the train accelerates for 200s from a start velocity of Om/s. The radius of the bend is 300m a) Calculate the maximum velocity of the train at the end of the straight track in m/s b) Calculate the radial velocity of the train when it is on the bend in rad/s c) If the mass of the train is 100 tonne, calculate the force acting on the train wheels when it is on the bend
