1- The roller coaster car has a brake and return system that has characteristics of a spring with a constant 45 Ibs / ft. If the car has an initial velocity of 3 ft/ s, determine the total force that the brake and return system must store. Assume that there is no friction, that the travel on the flat (from D to the spring) is 350 feet, and that the test weight of the car with passengers is 1000 Ibs. What does the sign of the answer mean?
