A thin 1 m long uniform rod with a total mass of 750g is suspended vertically at the upper end. The moment of inertia of the rod in respect to the center of mass is mL*2/12 (where L is the total lenght of the rod). A 9 g bullet is shot to the lower end of the rod and embeds there. The bullet speed before impact is 580 m/s. Calculate the amount of energy transfered to the heat during the...

A cylindrical rod of length 2.0 m, radius 0.5 m, and mass 1.5 kg has two spheres attached on its ends. The centers of the spheres are 1.0 m from the center of the rod. The mass of each sphere is 0.66 kg. The rod is capable of rotating about an axis passing through its center and perpendicular to the plane of the page, but the set up is stationary to begin with. A small mass of value 0.19 kgmoving...

thin rod of mass Mandlength Has a fixed rotation axis a distance L/6 from one end.(a) Using the parallel-axis theorem, find the moment of inertia of the roundabouts rotation axis. (b) Suppose the rod is held horizontally at rest and then released. Draw a free-body diagram of the rod at the moment of its release, and find its angular acceleration atthis moment. (Remember that gravity acts at the rod’scenter.)(c) Find the angular velocity of the rod as it swings through...

A playground merry-go-round has a radius of 1.5 m and mass of 200 kg, and turns with negligible friction about a vertical axle through its center. A child applies a constant force that produces a torque of 50 N·m to the merry-go-round. Its moment of inertia is given by I = ½MR2. The next four questions have to do with this rotating merry-go-round. Determine the angular acceleration of the merry-go-round in rad/s2. a. 0.047 rad/s2 b. 0.222 rad/s2 c. 0.965...
