Hey, this is so close to your earlier problems that I am getting worried. Better review the chapter !
anyway
0.30 revs is how many radians?
multiply by 2 pi
0.30 revs * 2 pi radians/rev = 1.88 radians
so it goes from 0 to 1.88 radians/second in 25.8 seconds
acceleration = change in velocity / change in time
= 1.88 rad/s / 25.8 s = (1.88/25.8) rad/s^2
A potter’s wheel moves from rest to an angular speed of 0.30 rev/s in 25.8 s.
Assuming constant angular acceleration,
what is its angular acceleration in rad/s2
?
Answer in units of rad/s^2

Yeah thank you and yeah i need to study
