1.	the engine of a train has to apply a force of 5000 Newton to overcome friction to run at a uniform rate of 90 km per hour what is the power developed by the engine.
Answer» GIVEN in that Force F = 5000 N velocity v = 90 km/h = 25 m/s Power is given by P = F.v = 5000 N × 25 m/s = 125000 W = 125 KW
