A mechanic uses a mechanical lift to raise a car. The car weighs 11,000 N. The lift raises the car 2.5 m.
KengaRu [80]

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 <em>at least  27,500 joules</em>.

A mass of 2000 kg is raised 5.0 m in 10 seconds what is the potential energy of the mass at this height?
kvv77 [185]

Answer:

A. 98,000 J

Explanation:

The gravitational potential energy of an object is given by

U = mgh

where

m is the mass of the object

g is the gravitational acceleration

h is the heigth above the ground

In this problem,

m = 2000 kg

g = 9.8 m/s^2

h = 5.0 m

Substituting into the equation, we find

U=(2000 kg)(9.8 m/s^2)(5.0 m)=98,000 J
