an external combustion engine has a power of 12kilowatt. the speed at which it raises a mass of 120 Kg is?
Dear Student,
Please find below the solution to the asked query:
Force applied on the engine to raise the mass = weight of the object = W = mg
Taking g = 10 m/s2
W = 120 × 10 = 1200 N
Now,
Power = Force × speed
12000 = 1200 × speed
speed = 10 m/s
Hope this information will clear your doubts about (Work and energy).
