Y = 180 - 51 -56 = 73
x = 180 - 73 - 72 = 35
x = 35 degrees
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
The quotient of 675 and 5 would be 135.
675/5=135
Hope this helps!
