Rotational Accel/Radians <<Solved>>
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
