43. A Mercedes-Benz 300SL (m = 1700 kg) is parked on a road thatrises 15° above the horizontal. What are the magnitudes of (a) the normalforce and (b) the static frictional force that the ground exerts on the tires? 44. Go Consult Multiple-Concept Example 9 to explore a model forsolving this problem. A person pushes on a 57-kg refrigerator with ahorizontal force of – 267 N; the minus sign indicates that the force pointsin the -x direction. The coefficient of static friction is 0.65. (a) If therefrigerator does not move, what are the magnitude and direction of thestatic frictional force that the floor exerts on the refrigerator? (b) Whatis the magnitude of the largest pushing force that can be applied to therefrigerator before it just begins to move?
