A train weighing 100 metric ton is running on a level track with a uniform speed of `72km h^(-1)` . If the frictional resistance amounts to `0.5kg` per metric ton, find the power of the engine

A train weighing 1000 quintals is running on a level road with a unifrom speed of 72km//h If the frictional resistance amounts to 50g wt. per quintal find power in watt, take g = 9.8ms^(2) .

A train of weight 10^(7)N is running on a travel track with uniform speed of 36 km h^(-1) . The frictional force is 0.5 kg f per quintal. If g = 10 ms^(-2) , power of engine is

A train of mass 100 metric tons is drawn up an incline of 1 in 49 at the rate of 36 kph by a engine. If the resistance due to friction be 10N per metric ton, calculate the power of the engine if the steam is shut off, how far will the train move before it comes to rest ?

A 50 metric ton train has to run at 72 kmh^(-1) . If the track is level and total resistance is (1)/(80) th the weight of the train, find the power of the engine.

A railway engine weighing 40 metric ton is travelling along a level track at a speed of 54 km H^(-1) What additional power is required to maintain the same speed up an incline of 1 in 49 Take g = 9.8 m//s^(2) and m u = 0.1 .

A truck of amss 10 ton is movng up an incline of 1 in 50 with a uniform velocity of 72 km/h. If the resistance opposing the motion of the truck due to friction is 5 kg per ton, the power of the engine is (g=10m//s^(2))

An engine accelerate a car of mass 800 kg to a speod of 72 km//h . If the frictional force is 10 N per tonne, the power developed by the engine is:

Two trains A and B of length 400 m each are moving on two parallel tracks with a uniform speed of 72 km h^(-1) in the same direction with A ahead of B . The driver of (A) , what was the originaldistance between them ?
