Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer: It would cost $150 for a party of 9 people and it would cost $260 for 20 people
Step-by-step explanation:
The number 9 falls in between 0<n<_ 12 so the cost is 150
The number 20 falls in between 12<n<_ 20 so the cost is 260
Well we know that total percentages always equals 100 so x + 45 = 100. You should get x = 55%
<em>Answer : </em><em>15 days</em>
<em />
<em>Explanation?</em>
<em>Well considering it takes them 3 days to make 8, we would divide 40 by 8 which is 5 and multiply 3 and 5 to get 15 days in total.</em>
