What is force of limiting friction and sliding friction?

Is rolling friction more than sliding friction ?

The limiting friction is

Out of stiatic friction limiting friction and dynamic friction which is largest ?

if mu_(s),mu_(k) and mu_(r) are coefficeints of static friction, sliding friction and rolling friction, then.

A 60kg is pushed horizontaly with just enough force to start it moving across a floor and the same force continues to act afterwards. The coefficient of static friction and sliding friction are 0.5and 0.4 respectively the accleration of the body is
