In the figure here, a 29 kg child stands on the edge of a stationary merry-go-round of radius 2.2 m. The rotational inertia of the merry- go-round about its rotation axis is 100 kg⋅m². The child catches a ball of mass 0.9 kg thrown by a friend. Just before the ball is caught, it has a horizontal velocity of magnitude 9 m/s, at angle = 38° with a line tangent to the outer edge of the merry-go-round, as shown. What is the angular speed of the merry-go-round just after the ball is caught? W = i Child Ball

A weather vane initially at rest has a moment of inertia of 0.104 kg · m2 about its axis of rotation. A 68.0 g piece of clay is thrown at the vane and sticks to it at a point 14.0 cm from the axis. The initial velocity of the clay is 27.5 m/s, directed perpendicular to the vane. Find the angular velocity of the weather vane just after it is struck.
The motion of spinning a hula hoop around one's hips can be modeled as a hoop rotating around an axis not through the center, but offset from the center by an amount h, where h is less than R, the radius of the hoop. Suppose Maria spins a hula hoop with a mass of 0.72 kg and a radius of 0.65 m around her waist. The rotation axis is perpendicular to the plane of the hoop, but approximately 0.43 m from the center of the hoop. (a) What is the rotational inertia of the hoop in this case?(b) If the hula hoop is rotating with an angular speed of 13.1 rad/s, what is its rotational kinetic energy?

A pendulum, with a mass of 6 kg block A is given in Figure 1. Pendulum is swinging through vertical position in the clockwise direction. The angular velocity and the angular acceleration of the block A is ωa = 8 rad/s, and αa = 0.2 rad/s2, respectively. At the given instant, a 100 − gram metal ball (shown as B) with a speed of v = 250 m/s hits the block A with an angle of β = 15◦. The metal ball becomes embedded in the block A. You can neglect the mass of the string that holds the pendulum A.a) What is the angular velocity ω2 of the pendulum immediately after the impact? b) What is the maximum angular deflection θ of the pendulum after the impact?c) Assume another case for the system at the same time instant given in Figure 1. This time the metal ball hits the block A with the same speed (v = 250 m/s), but with an angle of β = 0◦ However, this time, the coefficient of restitution is e = 0.6 (so they do not become embedded). Determine the velocities of the metal ball and the block just…
