A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform
density is placed upon a horizontal, frictionless surface. A small
rubber puck (mass 250 g) slides towards the bar with a speed (2
m/s) directed perpendicular to the bar. It collides perfectly
elastically with the bar at a distance (d) from the center of mass
of the bar in such a way that the puck rebounds with a velocity (1
m/s).

5. A half section of a uniform thin pipe of mass m 2 kg is at rest when a force P 40 N is applied at point A as shown. The static and kinetic friction coefficients are μ': 0.15 and μ"01, respectively. Determine (a) the angular acceleration, and (b) the magnitude and direction of the friction force between the thin pipe and the horizontal plane. The distance between the geometric center O and mass center G of the thin pipe...

Problem 4 A square object is constructed of four identical uniform thin sticks, each of mass m and length L, attached together. This object is hung on a hook at its upper corner. If it is rotated slightly to the right and then released, at what frequency will it swing back and forth? Hints: Find the distance from the hook to the center of mass of the object. Then find the moment of inertia of each stick with respect to...
