P. 3991. A solid cylinder of mass m and radius R is rotated with an angular speed of 0 as shown in the figure and placed carefully to a long enough slope at a distance of s measured from the bottom of the slope. The incline angle is . How far from the bottom will the cylinder move and with what speed will it reach the bottom if
a) =30o and =0.2;
b) =20o and =0.4?
Data: s=2 m, R=0.2 m, 0=100 s-1.
