Hi, can somebody help me out with this question: A car is stuck on the side of the road and the driver has only a long piece of non-stretchable rope. Seeing a tree 20 m away from the car he ties the rope to the tree and then to the car such that it is quite tight and any sag is negligible. The driver then pushes the rope at the midpoint of the rope with a push prependicular yet horizontal to the line made by the rope. What force does the rope exert on the car if the driver can push the rope to a distance of 2 m with a force of 600 N? I know (or atleast think) that I must use the similar triangles of the force and distance vectors. I have tried it many different times and i'm getting 3000 N being exerted on the car. Can anyone show me if its right. Thanks!
