Asolid cylinder of radius 11.0 cm rolls down an incline with slipping. the angle of the incline is 28°. the coefficient of kinetic friction on the surface is 0.370. what is the angular acceleration (in rad/s2) of the solid cylinder? (enter the magnitude.)

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
