Answer:
Step-by-step explanation:
<u>Let the capacity of tank is x</u>
- 1/5x + 9 = 7/10x
- 2/10x + 9 = 7/10x
- 5/10x = 9
- 1/2x = 9
- x = 18 gallons
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
