1O C A cart for hauling ore out of a gold mine has a mass of 439 kg , including its load. The cart runs along a straight stretch of B Track track that climbs a shallow 4.75° incline. A donkey, which is Rope trudging along and to the side of the track, has the unenviable job of pulling the cart up the slope with a 441 N force for a distance of 185 m by means of a rope that is parallel to the slope but makes an angle of 14.5° with the track. A „Track incline Model the rolling resistance of the cart as though it were Horizontal ground sliding on the track with a coefficient of friction of 0.0163.

9. If a horizontal force is applied to an object, how can you tell if an object will start moving? Your answer: O The object will start moving if any force is applied. O The object will start moving if the applied force is greater than the maximum static friction. O The object will start moving if the applied force is greater than the minimum static friction. O The object will start moving if the applied force is greater than the maximum kinetic friction. O The object will start moving if the applied force is greater than the minimum kinetic friction.

Which of the following sentence is not correct? The direction of friction is always perpendicular to the direction of the gravity force (weight) of the object. The direction of friction is always perpendicular to the normal force. The direction of friction is always parallel to the surface between objects. The direction of friction is always opposite to the direction of motion of the object. Question 3 Compared with the force needed to keep a box to slide at constant velocity on a coarse surface, to start the box sliding usually needs less force. same force. more force.
