An inspection robot has a weight of 600 N and moves at constant velocity across a level floor. A cable pulls the robot with a force of 150 N at 37∘ 37^\circ\,37∘ above the horizontal.
Use a scale drawing with 1.0 cm representing 30 N to determine the horizontal and vertical components of the force in the cable.
Calculate the size of the normal contact force exerted by the floor on the robot and the size of the total resistive force acting on the robot.
