Consider a science exhibit consisting of a wooden pole of length 1.3 m and mass 4.0 kg as shown in the figure below. The pole rotates fricionless-ly about a horizontal axis through the center. Two glass spheres of mass 4.2 and 2.1 kg are attached to the ends of the pole. After the pole is released from the horizonal position, what is its angular velocity when it swings through the vertical? O 2.0 kg 6. 1.0 m 2.0 kg 4.0 kg 4.0 kg (a) (b)

In orbit mechanics, the angular momentum is also an important quantity governing the satellite's motion. Assume planar motion, a satellite is orbiting around Earth center within a fixed plane. Thus it's motion is completely described by the distance r and the angle (relative to some reference direction). êo 0 (center of Earth) êr PO.. P (satellite) satellite's trajectory Obtain the satellite's angular momentum with respect to Earth center. For spacecrafts, the angular momentum (h) is h = Fx, it is independent of mass. What is the magnitude of h?

You throw a ball of mass 0.61 kg with speed 7.7 m/s at a cylinder of radius 0.22 m as shown. Theball hits the edge of the cylinder and sticks to it, and they spin about the cylinder’s central axis.What is the magnitude of the angular momentum of the ball about the center of the cylinder asthe ball approaches the cylinder?

4. An point-like object of mass m travels with speed vo towards the right, as seen in the figure below. It collides completely inelastically with the end of a uniform rigid rod of length L and mass M, which is hangs vertically from (and free to rotate around) a pivot point on the ceiling. m Vo M, L (a) What is the angular speed of the objects immediately after the col- lision? (b) Suppose the angular displacement of the objects from the pivot is small post-collision, what's the period of the pendulum?

A 5.0 kgkg, 68-cmcm-diameter cylinder in (Figure 1) rotates on an axle passing through one edge. The axle is parallel to the floor. The cylinder is held with the center of mass at the same height as the axle, then released. What is the magnitude of the cylinder's angular velocity when it is directly below the axle?

help pls asap not in scientific notation pls

Two big bugs, Buzz and Crunchy each of mass 0.65 kg, are siting on a spinning disk on a horizontal plane. Buzz is sitting halfway and Crunchy is sitting at the outer edge as shown. The radius of the disk is 9.5 m and it rotates once every 1.2 s. What is the magnitude of the net force on Buzz, in Newtons?
