Very urgent

The disk of 5 kg mass attached to a spring
shown in the figure is moving on a vertical plane.
k = 80 N/m
At a particular instant its total mechanical energy
is 108 Joules, its speed is 3 m/sec, its angular
4 N
speed is 1 Rad/sec, elongation in the spring is 0.8
m, and the spring constant is 80 N/m. The disk is
6 N
G
1.2 m above the reference line shown. Determine
4 N
(a) the radius of the disk, (b) angular acceleration,
1.2 m
and (c) horizontal and vertical components of
acceleration of the disk.
