1. The problem statement, all variables and given/known data Two blocks are connected by an extensible massless cord on an inclined plane as shown in the figure below. What is the tension in the cord pulling the lower block? What is the force pulling both the blocks? When I try to solve for tension 1st, I'm getting a negative answer... Here's my FBDs: http://i210.photobucket.com/albums/bb23/Kyashii628/fb.jpg My equations: for the 15 kg T- Fgx= ma T-314.0208114= 114.7 N T= -199.3208114 N Can someone tell me what I did wrong? Is the Fgx supposed to be pointing down the ramp instead of up the ramp?
