In which case (A, B or C) is the sailboat most likely to tip over sideways? Explain.
Solution:
The answer is Case A.
While it is the parallel component of force which propels the boat forward, it is the perpendicular component of force which tips the boat over. This component of force is greatest in Case A as seen in the diagram.
Problem 3. Consider the tow truck below. If the tensional force in the cable is 1000 N and if the cable makes a 60-degree angle with the horizontal, then what is the vertical component of force that lifts the car off the ground?
