Explanation The free body diagram of the cast-leg system is given as, Write the expression for the mass of the upper leg. m u l = 1 2 p m Here, m u l is the mass of the upper leg, p is the mass percent of the both the legs, and m is the mass of the body. Substitute 0.215 for p , and 74 kg for m to get m u l . m u l = 1 2 ( 0.215 ) ( 74 kg ) = 7.955 kg Write the expression for the mass of the lower leg. m l l = 1 2 p m Here, m l l is the mass of the lower leg. Substitute 0.140 for p , and 74 kg for m to get m u l . m l l = 1 2 ( 0.140 ) ( 74 kg ) = 5.18 kg Write the expression for the coordinate of the center of mass. x c m = x u l m u l + x l l m l l + x cast m cast m u l + m l l + m cast Here, x c m is the coordinate of the center of mass, x u l is the coordinate of the upper leg, x l l is the coordinate of the lower leg, x cast is the coordinate of the cast, and m cast is the mass of the cast

Part C Find the height yi from which the rock was launched. Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g. Thus, the problem becomes one of…
