1. What is a given= 0.215 [ms^-2] and diameter of disk with uniform mass distribution= 19.5 [cm].
theta= ?
2. Using information found in previous question, if the dropping mass is 195 [g], then what is T?
T= ? [Nm]
(a)
The acceleration is a = 0.215 m /s2
The radius of the disk is,
r = diameter / 2
= 19.5 cm /2
= 0.0975 m
Hence, the angular acceleration is,
? = a / r
= 0.215 m/s2/ 0.0975 m
= 2.205 rad/s2

(b)
The required tension can be calculated as,
T = m a
= 0.195 kg * 2.205 rad/s2
= 0.4299 N.m
= 0.43 N.m
