Part A Learning Goal: To be able to describe the motion of rigid bodies by applying the conservation of linear and angular momenta. If the sum of all the linear impulses acting on a system of connected rigid bodies is zero, the linear momentum of the system is conserved. Mathematically, this relationship is expressed as syst. linear momentum syst. linear momentum and is called the conservation of linear momentum. If the sum of all the angular impulses (created by the external forces that act on the system) is negligible or zero, then the angular momentum of a system of connected rigid bodies is conserved about the system's center of mass or about a fixed point. Mathematically, this relationship is expressed as syst. angular momentum syst. angular) momentum and is called the conservation of angular momentum. Which of the following scenarios demonstrate the conservation of either linear or angular momentum? Check all that apply. A parent pushes a merry-go-round and, consequently, it spins faster. An ice skater tucks in her arms during a spin and her angular velocity increases. From opposite sides of a room, two identical balls of putty move toward each other, without friction, at the same velocity and, eventually, they collide; the result is one ball of putty with zero velocity. A penny is dropped from the top of a building and its velocity increases as it falls due to the acceleration from gravity. Submit Previous Answers Figure 1 of 1 B Part B Correct A pendulum consists of a slender rod, AB, of weight W = 9.80 lb and a wooden sphere of weight W = 26.6 lb (Figure 1) The length of the rod is d₁ = 8.30 ft and the radius of the sphere is R = 0.450 ft. A projectile of weight W₂ = 0.500 lb strikes the center of the sphere at a velocity of v₁ = 863 ft/s and becomes embedded in the center of the sphere.
