Question

If Power of an engine is 60 kilowatt (kW) and a force of 2000 N is applied on it. With what velocity the engine will move? ​

Answer 1

Answer:

Power=work/time

Work=F×S

Power=F×S/t

Power=F×v where v is the velocity as it is rate of change of displacement

40000=20000×v

v=40000/20000=2m/s.
