"A student's car stalls right in front of a speed bump while she is on her way to physics class. To pull it over the bump, she ties a cable to her bumper and to a nearby tree, and pulls with a force, F, of 70.0 pounds (311 N) at the midpoint in a perpendicular direction. If theta is 12.4 degrees, what is the size of the force pulling the car (in pounds)?"

Please see the attachment also.
The applied force will produce a tension along the string. Since it is applied at the midpoint, we will say T acts on each part of the ...
