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...

A uniform thin rod of length 0.65 m and mass 3.4 kg can rotate
in a horizontal plane about a vertical axis through its center. The
rod is at rest when a 3.8 g bullet traveling in the rotation plane
is fired into one end of the rod. As viewed from above, the
bullet's path makes angle θ = 60° with the rod. If the
bullet lodges in the rod and the angular velocity of the rod is
11.0 rad/s...

Chapter 11, Problem 053 GO A uniform thin rod of length 0.61 m and mass 3.3 kg can rotate in a horizontal plane about a vertical axis through its center. The rod is at rest when a 4.4 g bullet traveling in the rotation plane is fired into one end of the rod. As viewed from above, the bullet's path makes angle 9 -60° with the rod. If the bullet lodges in the rod and the angular velocity of the...

A 10g bullet is fired horizontally at 1000m/s towards the vertical uniform thin rod (mass 1kg and lengths 1m) free to rotate about an axis of rotation at its upper end. The bullet strikes the rod (and lodges in it) at distance d=20cm below the rod’s center of mass. What is the angular velocity of the rod-bullet system immediately after the collision? Will the rod make a complete revolution? If yes, what will be its angular velocity at the highest...

A uniform rod of mass 5 kg and length 1.5 m is pivoted about its center. The rod is struck at one end with a hammer; during the blow an average force of 1000 N acts for 0.01 seconds. What is the angular velocity of the rod just after the impact, if the rod was initially at rest? Use Irod = (1/12)ML2.

A uniform thin rod of length 0.500 m and mass 4.00 kg is attached to a pivot at one end. The other end of the rod is attached to a uniform sphere with a mass of 2.00 kg and a radius of 0.100 m. The rod and sphere initially hang vertically. A bullet with a mass of 5.00 g is fired horizontally at a speed of 200 m/s into the center of the sphere. The bullet embeds itself in the...

A thin, uniform, rectangular sign hangs vertically above the door of a shop. The sign is hinged to a stationary horizontal rod along its top edge. The mass of the sign is 2.40 kg and its vertical dimension is 75.0 cm. The sign is swinging without friction, becoming a tempting target for children armed with snowballs. The maximum angular displacement of the sign is 25.0° on both sides of the vertical. At a moment when the sign is vertical and...
