It is by gaining! I just learned this in school. Hope this helps:)
Answer:
Angular velocity (w) = 8.86 rad/s
Explanation:
Angular velocity (w) = 
g= 9.81 m/s
R= 0.5
hi (initial depth) = 0.5m
Hence=
= 8.86 rad/s
Answer:
0.4rad/s²
Explanation:
Angular acceleration is the time rate of change of angular velocity . In SI units, it is measured in radians per second squared (rad/s²)
w1 = 4rad/s, w2 =2rad/s, t = 5sec, r = 0.30m
a = ∆w/t
a = (w2 - w1)/t
a = (2 - 4)/5 = -2/5 =
a = - 0.4rad/s²
The -ve sign indicates a deceleration in the motion
Good luck
