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
[tex]U=(2000 kg)(9.8 m/s^2)(5.0 m)=98,000 J[/tex]
Answer:
0 J
Explanation:
the object isn't moving, there is no kinetic energy. This question is worded poorly and made this not obvious.
