Question

A 1100- car is held in place by a light cable on a very smooth (frictionless) ramp, as shown in the figure (Figure 1) . The cable makes an angle of 31.0 above the surface of the ramp, and the ramp itself rises at 25.0 above the horizontal.

Answer 1

So far i have determined the following equations from the my force body diagrams. T(cos(31)) - mg(sin(25)) = 0 N - (mg(cos(25)) + (T(sin(31))) = 0 to solve for tension you rearrange the first equation to get T(cos(31)) = mg(sin(25)) so if you solve for the horizontal component of gravity you will be able to determine the tension of the string. i have tried my following answer (which comes out to 1426N) but i am incorrect. if anyone can please point out what i am missing i would be really appreciate it.
