Answer:
Step-by-step explanation:
It is A
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
M<ABC= (AD+CE)/2=(100+45)/2=145/2
m<ABC=72° 30'
Answer:
Michael travels a total of 756 miles each year.
Step-by-step explanation:
If you want the total number of miles he travels(to and from the house combined), just multiply 84 by 9.
