A steam turbine is generally considered the most efficient type of steam engine and can often exhibit an efficiency as high as 35
percent. If the useful work done or output each second by a steam turbine with this efficiency is 6,789 , how much work must the
steam do on the turbine?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
