Suppose your car was mired deeply in the mud and you wanted to use the method illustrated in the figure to pull it out.
(a)
What force in newtons would you have to exert perpendicular to the center of a rope to produce a force of 10,000 N on the car if the angle is 1.80°?
This answer has not been graded yet.
(b)
Real ropes stretch under such forces. What force in newtons would be exerted on the car if the angle increases to 6.20° and you still apply the force found in part (a) to its center?
