Question

A train of 100 tonnes is pulled by an engine on level track at constant speed of 45km per hour . The resistance due to friction is 10 kg per tonne. Find the horse power of the engine.

Answer 1

An engine can pull a 500 metric ton load up an inclined plane rising 1m in 100m of horizontal distance with a speed of 10m per second. The frictional force offered by the plane is 2000 N. What is the power of the engine? Given g = 9.8 meters per second squared.
