1. Here's our force diagram from Part 1: In this drawing, we've rotated the coordinate axes so the x-axis is parallel with the ramp surface and the y-axis is perpendicular. Now most of the forces are aligned with the axes, except one. Which force is not aligned with the new axes? Hint: Note: our textbook would label F_{string}Fstring as either F_TFT or just TT for the tension force. F_gFg , the force of earth's gravity on the object, also known as the weight w of the object. F_NFN, the normal force (sometimes labeled n ) on the object by the ramp surface. F_TFT, the tension force on the cart by the string
