Sagot :
The car gains Ep=mass*g*difference_in_height=11000*2.5=27500 J
Answer A
Answer A
Potential energy = (weight) x (height)
After the car has been raised 2.5 meters, it has
(11,000) x (2.5) = 27,500 Joules
MORE potential energy than it had before it was lifted.
That's the energy that has to come from the work you do to lift it.
Since no mechanical process is ever 100% efficient, the work required
to accomplish this task is at least 27,500 joules.
