To find the displacement between t=0 and t=1, we want to plug 0 & 1 into the equations, then find the different in the answers.
<u>When t = 0:</u>
x = 4 cos(π(0)+π/4) → π · 0 = 0, so therefore:
x = 4 cos (π/4) → cos (π/4) = √2/2
x = 4 (√2/2)
x = 4√2/2 → 4 divided by 2 = 2, so we can simplify this to
x = 2√2
<u>When t = 1:</u>
x = 4 cos(π(1)+π/4) → π · 1 = π, so therefore:
x = 4 cos (π + π/4) → π + π/4 = 5π/4, so therefore
x = 4 cos (5π/4) → cosine of 5π/4 = -√2/2
x = 4 · -√2/2
x = -4√2/2 → -4 divided by 2 = -2, so we can simplify this to
x = -2√2
<u>Answer</u>: Then, we find the difference between x(0) and x(1), which is x(1)-x(0) =
-√2/2 - √2/2 = <u>-√2</u>
We actually recently learned about this in lecture. Although the president may seem like they have unlimited power in Congress, there's three separate powers called checks and balances that help keep equal and fair treatment among Americans and our economy. In order for an idea to be implemented into a law, the idea must pass from Congress, to the Senate, to the president, and then back to Congress again for a final answer. They have to sit down an negotiate the reasons why the supposed law or proposals that's being pitched will benefit the country in a safe, humane, and mindful way. The president can veto a proposed bill if he or she does not believe it benefits our country but Congress has unlimited chances to send the bill back. This can go on and on forever until both the president and executive branch reach a leveled consensus on the proposal.
