A hydraulic lift used at an automotive repair shop raises a 1000-kilogram car two meters off of the ground. What is the potential energy given to the car?
A 1000 J
B 2000 J
C 9800 J
D 19,600 J

Answer:

D. 19,600 J  

Explanation:

In our case, we are to solve for the potential energy of the car above the hydraulic lift. For potential energy, we will use the formula:

PE = mgh

where

PE      is the potential energy, unit is in N.m or Joules (J)

m       is the mass of the car, unit is in kg

g        is the acceleration due to gravity, 9.8 m/[tex]s^2[/tex]

h         is the height lifted by the hydraulic to the car, unit is in meters (m)

For the given information

m = 1000 kg

h = 2 m

PE = ?

Solving the problem

Let us use the formula for potential energy then substitute the given information, we have:

PE = mgh

PE = (1000 kg)(9.8 m/[tex]s^2[/tex])(2 m)

PE = 19,600 J

Therefore, the potential energy of the car is 19,600 J.
