1. The problem statement, all variables and given/known data A 1070-kg 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. http://imgur.com/gkOQuRq "Draw the force vectors with their tails at the front bumper of the car. The location and orientation of your vectors will be graded. The exact length of your vectors will not be graded." 2. Relevant equations 3. The attempt at a solution The problem states "a frictionless surface", so i didn't add a friction vector. Tension can only be in the cable( as far as i know?) so i put a tension vector along the cable. The weight vector i put straight down, and the normal vector perpendicular to the surface. I figured that the car is being dragged along the ramp, so i put a thrust vector along the dotted line. It looks like this as of now http://imgur.com/Geg71cj I only have two attempts remaining. I've tried a lot of different methods.. The only thing I can think of at this point is to take out the thrust vector and see if that works.
