A hole, and people die if they fall in there.
GPE= 70.56 J -------------------> GPE= mgh-------------> X= height
70.56 = 6(kg) * 9.8(m/s/s) * X
70.56 = 58.8X
70.56/58.8= 58.8X/58.8
X= 1.2
The height is 1.2 feet or meters (whatever unit you are using in this problem)
When speed is combined with strength it is power
Answer:
72.22 N
Explanation:
F = weight
m = mass of body
M = mass of earth
R = radius of earth
G = universal constant of gravitation
F_1= 650 N
F_1 = GMm/R^2
two earth radius above the surface of the earth:
F_2= GMm/(3R)^2= GMm/9R^2= F_1/9= 650/9
=72.22 N
