The gravitational potential energy has the formula:
PE = mgh
where PE is in joules
m is the mass of the object in kg
g is the acceleration due to gravity
h is the height in m
since you did not give the value of h, i cannot fully answer your quesstion.
PE = (58/1000 kg) (9.81m/s2) h
PE = 0.57h
just substitute the value of h in the equation
Answer:
The answer is "-72 k".

Calculating the area:
![=i[8(0)-8(0)]-j[(0-0)]+k[(0-9(8))]\\\\=i[0-0]-j[(0)]+k[(0-72)]\\\\=i[0]-j[(0)]+k[(-72)]\\\\=-72 \ k](https://tex.z-dn.net/?f=%3Di%5B8%280%29-8%280%29%5D-j%5B%280-0%29%5D%2Bk%5B%280-9%288%29%29%5D%5C%5C%5C%5C%3Di%5B0-0%5D-j%5B%280%29%5D%2Bk%5B%280-72%29%5D%5C%5C%5C%5C%3Di%5B0%5D-j%5B%280%29%5D%2Bk%5B%28-72%29%5D%5C%5C%5C%5C%3D-72%20%5C%20k)
