Question 5. In Experiment 2 (see Figure 2) the cart rolls up and down an inclined track at an angle 0. It experiences only a component of the gravitational acceleration, gx. By looking this figure carefully, derive the expression for gx in terms of the known or measurable parameters g, h, and d. 10 d 9x |h=hR-hL e H hL hR Figure 2. Experimental setup for experiment
