Question

Transcribed Image Text:As part of a carnival game, a my = 0.653 kg ball is thrown at a stack of 23.8 cm tall, mo = = 0.363 kg objects and hits with a
perfectly horizontal velocity of Ubi = 10.8 m/s. Suppose that the ball strikes the topmost object. Immediately after the collision,
the ball has a horizontal velocity of bf = 3.10 m/s in the same direction, the topmost object has an angular velocity of
@= 1.63 rad/s about its center of mass, and all the remaining objects are undisturbed. Assume that the ball is not rotating and
that the effect of the torque due to gravity during the collision is negligible.
If the object's center of mass is located r = 16.7 cm below the point where the ball hits, what is the moment of inertia I, of the
object about its center of mass?
What is the center of mass velocity Uo.cm of the tall object immediately after it is struck?

Opposing players strike the puck with a hand-held round "paddle" (shown in red). In one case, while playing air hockey, the puck comes toward you with a speed of 0.8 m/s at an angle of 30° above the -x axis in the xz plane. You strike it with your paddle, and after the collision, the puck travels in the +x direction with a speed of 2.9 m/s toward the opponent's goal. The mass of the puck is 0.020 kg.arrow_forward
