..ooo Sprint 3:53 PM session.masteringphysics.com c + g Nea Thursday... 4:41 until... myBoiseSt...Pearson's.. Mastering... Masteri.Here's A G. CH04 Problem 4.68-71 Problem 4.68-7 yor car is stuckin the mud and you don't have a winch to pui out, you can use a poce of rope and a tee to do the trick First, you te one end ofthe rope to your car and the other to a tree, then pull as hard as you can on the middle of the rope, as shown in the figure. This technique applies a force to the car much larger than the force that you can apply directly To see why the car experiences such a large force, look at the forces acting on the center point of the rope, as shown in the figure. The sum of forces is zero, thus tension is much geater than the force you apply ItiS this tenson force that acts on the car and, with luck, pulls free Part A The sum of the tree forces acting on the center point of the rope assumed to be zero because O This point has a very small mass. Tension forces in a rope always canoel This point is not accelerating The angle of deflection is very small My Answers Give Up Part B When you are pulling on the rope as shown, what is the approximate direction of the tension fonce on the tree? North South O East My Answers Give Up Part C Assume that you are pulling on the rope but the car is not moving What is the appeoximate direction of the force of the mud on the ca? South O EastExplanation / Answer
A) this point is has a very small mass
F= mass x acceleration if mass is very smal force is almost zero
B) East
C) east
D) Equqal to the force of the rope on the car
newtons 3rd law equal and opposite force
