Answer:
v= 5/6
Step-by-step explanation:
You have to divide -6 on both sides to isolate the variable V. Then it would become -5/-6. The negative signs cancel out.
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
Answer:
2.5
Step-by-step explanation:
The radius is half of the diameter. 5 / 2 = 2.5
For first one
Y=6x+21 can’t be changed
X=y/6-7/2
for the second
X=-12+3y
Y=4+x/3
