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.
