1.	a train of mass 610^2 metric tones is pulled by a locomotive. the speed of the train will be 36 kph. the locomotive pulls the train on the level track, whose mass is 125 metric tones. the force of friction acts on the locomotive and the train is 110 newton per metric tonne. calculate the power of the locomotive
Answer» Hey mate here is yours answer Mass of the train is, m = 105 kg Uniform speed of the train is, u = 72 km/h = 20 m/s Frictional FORCE PER metric ton is = 0.5 × 9.8 N = 4.9 N Therefore, frictional force on the train = 4.9 × 100 = 490 N Since, the train has to overcome this frictional force to maintain a constant speed, the power is given by, Power = (force)(speed) = 490 × 20 = 9800 W please follow me
