CONTEXT-RICH To prevent damage to her shoulders, your elderly grandmother wants to purchase the rug beater (Figure 9-50) with the lowest moment of inertia about its grip end. Knowing you are taking physics, she asks your advice. There are two models to choose from. Model A has a 1.0-m-long handle on a 40-cm-edge-length square, where the masses of the handle and square are and respectively. Model B has a 0.75-m-long handle and a 30-cmedge- length square, where the masses of the handle and square are and respectively. Which model should you recommend? Determine which beater is easier to swing from the very end by computing the moment of inertia for both beaters.
