**Rotational Accel/Radians <<Solved>>**

## Homework Statement

Question 1)

18. Convert the following measurements to radians.

c) the motion of an hour hand in 4.4 h = 2.3 Rad

d) Earth’s rotation in 28.5 h = 7.5 Rad

<<<<<<figured it out, thanks SammyS for that obivious yet overlooked detail lol :D >>>>>>>>

Question 2)

A flywheel rotating at 18.0 rad/s slows to a

stop in 22.0 s. Find

a) its angular acceleration. = -18.18rad/sec^2

b) the number of radians it turns before

stopping. 198 rads

c) the number of cycles it completes in

this time. 31.5 Cycles

d) the angular speed after 8.7 s. 11rads/sec

*though i have a feeling this isn't the end of my issues lol, if anyone knows of an awsome site/article anything on rotational work please let me know, because I've been searching lol*

Thanks sammyS
