The equation f = v + 80 represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, overtime, t.Which is an equivalent equation solved for t?...A) t = f - v/aB) t = f - a/vC) a(f - v)D) v(f - a)
Accepted Solution
A:
Answer: A) t = (f -v)/aStep-by-step explanation:Undo the operations done to t, in reverse order. Here, t is multiplied by "a" then the product is added to v.To solve for t, first you undo the addition of v by subtracting v from both sides of the equation. f = v + at f - v = at . . . . . subtract vThen you undo the multiplication by "a" by dividing both sides of the equation by "a": (f - v)/a = t . . . . . . sort of matches choice A_____Please note that the parentheses are required. f -v/a is something quite different. If this is typeset, the fraction bar does the grouping. If it is written in plain text, parentheses are required for grouping.[tex]t=\dfrac{f-v}{a}[/tex]
