Need answer within 20minutes. Don't copy that is wrong
.A train having a mass of 400 t travels at a constant speed along a straight track. At that speed, the tractive force required to overcome friction and wind resistance is 5 mN/N (or 5 N/kN). Calculate the tractive effort required to maintain the same speed: (a) on a level track, (b) up an incline of 1 in 150 and (c) down an incline of 1 in 300..
