Q5. As shown in Fig. 5, a uniform sphere of mass m = 8 kg and radius r rolls without slip toward a large crate with mass M = 80 kg that rests on top of a rubber mat nailed into the ground. The coefficient of friction between the crate and the mat, 1 = 0.75. A spring with stiffness k is attached to the crate at a height h = 0.85m above the mat, and the crate's mass centre...

Pre-Lab Assignment 1. Draw separate free-body diagrams for each of the masses from Figure 6.1. Assume that mi > m2. Figure 6.1 2. Using the free-body diagrams for each mass, m, and m2, develop an equation for the acceleration of the system, in terms of mì, m, and g. Do this by using Newton's second law in the vertical direction to analyze each mass separately. This will give two equations that can be solved for acceleration. Hint: You may find...
