Answer: the formula is r you have it right there
Step-by-step explanation:
Answer:
For this case we have the following equation:
a = v ^ 2 / r
From here, we must clear the value of speed.
We have then:
v ^ 2 = a * r
v = root (a * r)
the formula for the velocity is:
-5x + 20 = -30
-5x = 10
x = -2
40,000 is 39,265 rounded to the nearest ten thousands
