For the sake of simplicity, we can model a baseball swing as a bat joined to the end of a block that rotates about one end (left end in the figure below). In this simplified model, the rigid body of the block plus the bat has a total weight of W = 26 lbs, and a mass center G located at k = 1.417 ft. The baseball has a weight of 5 oz (0.3125 lbs) and impacts the bat at location a = 2.75 ft. At the moment of impact, the batter is swinging the bat at w = 10.5 rad/s, and the baseball is traveling at 60 mph. According to research, the coefficient of restitution for a baseball is e = -0.546. Using the given momentum and impulse diagrams below, determine the velocity of the ball immediately after impact. Note: V₁ is not a momenta or an impulse, but you will need to know the velocity of point A on the bat for your impact analysis. Hint: Don't forget that VG and VA are both related to w.

5) In ice figure skating, a couple execute a “top” (see picture). The centre of mass of the woman (58 kg) is situated 1.3 m from the axis of rotation which is vertical and passes through the centre of mass of the man (85 kg). They are spinning at a constant angular velocity equal to 3.1415 rad/s and the man and woman have moments of inertia, about their own centres of mass, equal to 1.6 and 2.5 kg.m2 respectively. Then the woman grabs the neck of the man. At this point, her moment of inertia decreases to 1.4 kg.m2 and her body centre of gravity is 0.9 m from the axis of rotation. Determine the new angular velocity. Hints: This is a conservation of angular momentum problem, and needs the parallel axis theorem to determine moments of inertia about the axis of rotation. The skaters are moving as one body with one angular velocity, but they each have their own moments of inertia given relative to their own CoMs. For the man, that’s fine…the axis they’re rotating about passes through his…
