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:52-12=$40

Using permutations, it is found that there are 12 ways to pick a sequence of two different letters of the alphabet that appear in the word Crab
.
The order in which the letters appears is important, as for example, ab is a difference sequence than ba, hence the <em>permutation formula</em> is used.
Permutation formula:
The number of possible permutations of x elements from a set of n elements is given by:
In this problem, 2 letters are picked from a set of 4, hence:
There are 12 ways to pick a sequence of two different letters of the alphabet that appear in the word Crab
.
