tankabanditka [31]

Answer:

i believe its 9.09

Step-by-step explanation:

i did this problem 3 different ways

first i put it all in a calculator and got 9.09

then i did 0.81/0.09 = 9+ 0.81 = 9.81/9 = 1.09

finally i did 0.81/0.09 = 9 0.81/9 = 0.09

9+ 0.09 = 9.09

therefore 9.09 is what i believe the answer is

i hope this helps you!

A wheel initially has an angular velocity of 18 rad/s, but it is slowing at a constant rate of 2 rad/s 2 . By the time it stops,

Kaylis [27]

Answer:13 revolution

Step-by-step explanation:

Given data

Wheel initial angular velocity $\left ( \omega \right )$ =18 rad/s

Contant angular deaaceleration $\left ( \alpha \right )$ =2 $rad/s^2$

Time required to stop wheel completely=t sec

$\omega =\omega_0 + \aplha t$

0 =18 + $\left ( -2\right )t$

t=9 sec

Therefore angle turn in 9 sec

$\theta$ = $\omega_{0} t$ + $\frac{1}{2}$ $\left ( \alpha\right )t^{2}$

$\theta$ = $18\times 9$ + $\frac{1}{2}$ $\left ( -2\right )\left ( 9\right )^2$

$\theta$ =81rad

therefore no of turns(n) = $\frac{81}{2\times \pi}$

n=12.889 $\approx$ 13 revolution
