13 An object of mass m slides down a hill of height h of certain arbitrary shape and after travelling a horizontal path stops because of friction The friction coefficient is different for different segments for the entire path but is independent of the velocity and direction of motion The work that a force must perform to return the object to its initial position along the same path is a mgh b 2 mgh d mgh c 4 mgh
