Answer: What are the answer options?
Explanation:
It is important to look at all the information's that are given in the question very closely. Let us write them write first.
Radius of the spa = <span>5/√2-1 feet
Now
Perimeter of the circle = </span><span>2πr
= 2</span>π (5/√2-1)
= <span>π(5/(√2-1)*(√2+1)/(√2+1) </span>
<span> = 2π(5/(√2+1))/(2-1) </span>
<span> = 10π(√2+1)
I hope that the procedure is clear enough for you to understand.</span>
<span>Under favorable conditions, including reaction time, a motor vehicle with good brakes going 50mph can be stopped within about 230 feet. </span>
Since a motor vehicle which is having good brakes, and the speed is not much high, so within 230 feet, It can be stopped including the reaction time.
Answer:
No there is no displacement observed so no work done
