A cable pulls a box with force of 5 kN and raises it at the rate of `2 ms^(-1)`. What is the power of the engine providing tension to the cable?

An engine, working at a constant rate, is pulling a train of mass 500 tonne along a plane of inclination sin ^(-1) (1/(100)) . If the frictional force per metric tonne is 49 N and the train is moving with a velocity of 10 m *s^(-1) , what is the power of the engine in kilowatt ? [ 1 tonne (metric ton) =1000 kg]

The engine of a train has to apply a force of 5000 N to overcome friction to run at a uniform rate of 90 km *h^(-1) . What is the power developed by the engine ?

An electric motor in a crane while lifting a load produces a tension of 4000 N in the cable attached to the load. If the motor is winding the cable at the rate of 3ms^(-1) , the power of the motor espressed in kilo watt units must be

An electric motor creates a tension of 4500 newton in a hoisting cable and reels it at the rate of 2 m//s . What is the power of the motor ?

A electric motor creates a tension of 4500 N a hoisting cable and reels it at a rate of 2m*s^(-1) . Calculate the power of the motor.

A railway engine of mass 50 tons is pulling a wagon of mass 40 tons with a force of 4500N . The resistance force acting is 1N per ton The tension in the coupling between the engine and the wagon is .

A railway engine of mass 50 tons is pulling a wagon of mass 40 tons with a force of 4500N. The resistance force acting is 1N per ton. The tension in the coupling between the engine and the wagon is
