The question as text
An electric train of mass 1.5 × 104 kg travels up a slope at a constant speed as shown in Figure 4.1. X train Y Figure 4.1 At point X, the train has gravitational potential energy 7.4 MJ. At point Y, the train has gravitational potential energy 13.0 MJ. The train takes a time of 52 s to move from X to Y. The kinetic energy of the train is 1.3 × 105 J.
