Unformatted text preview: 7.30: The friction force has magnitude k mg = (0.20)(30.0 kg )(9.80 m/s 2 ) = 58.8 N. a) For each part of the move, friction does - (58.8 N)(10.6 m) = -623 J, so the total work done by friction is - 1.2 kN. b) - (58.8 N)(15.0 m) = -882 N. c) The net work done by friction depends on the path, so friction is not a conservative force. ...
