Can the coefficent of friction be more than one

Statement I: The coefficient of friction can be greater than unity. Statement II: The force of friction is dependent on normal reaction and the ration of force of friction and normal reaction cannot exceed unity.

Can the coefficient of restitution ever be greater than 1 ?

Three solid cylinders A, B and C each of mass m and radius R are allowed to roll down on three inclined plane A', B' and C' respectively (each of inclination theta ) such that for A' and A coefficient of friction is zero, for B' and B coefficient of friction is greater than zero but less than (tan theta)/3 and for C' and C coefficient of friction is more than (tan theta)/3 . On reaching bottom of the inclined plane

A 2 kg object is slide along a rough floor (coefficient of sliding friction = 0.3) with initial volocity (10 m//s) hat i . Describe the motion of the object relation to car assuming that the coefficient of static friction is greater than 0.5 .
