Answer:
t = 27.5
Explanation:
Well to solve for t we need to combine like terms and seperate t.
So 3+5= 8
8 - 220t = 0
We do +220 to both sides
8 = 220t
And now we divide 220 by 8 which is 27.5
Hence, t = 27.5
It changes at a rate of 4/3 meter per second
In the given figure below we have
Solving for Y given we get
Answer: A 2 square root 3
a=v-u/t
a=245-230/7
a=2
529 Hz
595(343-20)/(343 + 20) = 529
