An athlete swings a ball, connected to the end of a chain, in a horizontal circle. the athlete is able to rotate the ball at the rate of 8.13 rev/s when the length of the chain is 0.600 m. when he increases the length to 0.900 m, he is able to rotate the ball only 6.04 rev/s. (a) which rate of rotation gives the greater speed for the ball? 6.04 rev/s 8.13 rev/s (b) what is the centripetal acceleration of the ball at 8.13 rev/s? m/s2 (c) what is the centripetal acceleration at 6.04 rev/s? m/s2

Answer from: katlyn10289

(a) 6.04 rev/s

The speed of the ball is given by:

v=\omega r

where

\omega is the angular speed

r is the distance of the ball from the centre of the circle

In situation 1), we have

\omega=8.13 rev/s \cdot 2\pi = 51.0 rad/s

r = 0.600 m

So the speed of the ball is

v=(51.0 rad/s)(0.600 m)=30.6 m/s

In situation 2), we have

\omega=6.04 rev/s \cdot 2\pi = 37.9 rad/s

r = 0.900 m

So the speed of the ball is

v=(37.9 rad/s)(0.900 m)=34.1 m/s

So, the ball has greater speed when rotating at 6.04 rev/s.

(b) 1561 m/s^2

The centripetal acceleration of the ball is given by

a=\frac{v^2}{r}

where

v is the speed

r is the distance of the ball from the centre of the trajectory

For situation 1),

v = 30.6 m/s

r = 0.600 m

So the centripetal acceleration is

a=\frac{(30.6 m/s)^2}{0.600 m}=1561 m/s^2

(c) 1292 m/s^2

For situation 2 we have

v = 34.1 m/s

r = 0.900 m

So the centripetal acceleration is

a=\frac{v^2}{r}=\frac{(34.1 m/s)^2}{0.900 m}=1292 m/s^2

Answer and Explanation:

The Preparation of horizontal analysis for 2022 using 2021 as the base year is prepared with the help of a spreadsheet.

Horizontal analysis is a method for the analysis of financial statements that indicates fluctuations in the amount of the related products over a period of time. It is a valuable instrument for determining trend situations.

So, with the help of the spreadsheet, we will be able to find the net income by using the formulas.

Increase in net Operating income = $14,600

Explanation:

Sales

i. 8000 units X $220

=$1,760,000

ii. 8200 units X $220

=$1,804,000

Variables expenses

i. 8000 units X $66 = $528,000

ii8200 units X $72 = $631,400

Contribution margin

CM=Sales -Variables expenses

i. 1,760,000 - 528,000=

$1,232,000

ii. 1,804,000 - 631,400

=$1,172,000

Our Fixed expenses are

i. $991,000

ii. $917,000

Therefore Net operating income = Contribution margin - Fixed expenses

i. 1,232,000 - 991,000

=$241,000

ii. 1,172,600 - 917,000

=$255,600

From the answers above, there is an increase of $14,600 as a difference between $241,000 and $255,600 which are the Net Operating income.
