Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules
20-6.25-3.7-1.25-1.25= $7.50
Has has $7.50 left over.
