measured angle - 22.360 measured mass of cart : 507.79 static coefficient of fRection = 0.564 3. Predict the minimum mass of the hanging basket that will barely balance the cart, before it begins to slide down the inclined plane. Specifically, draw separate free body diagrams in the space below for the cart and the hanging basket. Apply Newton's laws to calculate the specific basket mass that should barely balance your cart. Use your measured angle, the measured mass of your cart, and the static coefficient of friction indenmeadehad mergeabove. predicted mass of basket
