A Jeep is stuck in the mud. The driver has a winch that can pull on its cable with a force of 35,000 N. The driver loops the cable through a pulley attached to a tree, then attaches the end of the cable to his Jeep.
What is the magnitude of the maximum force that can be exerted on the Jeep by this cable arrangement?

Answer:
F_net =70000 N
Explanation:
The driver has a winch that can pull on its cable with a force of 35,000 N.
Tension on both sides of the cable balances the 35,000 N force.
Therefore,
F_net =2T
F_net =2*35,000
F_net =70000 N
