A uniform thin rod of length 0.97 m and mass 2.2 kg lies in a horizontal plane and rotates in that plane about a pivot at one of its ends. The rod makes one rotation every 0.29 second and rotates clockwise as viewed from above its plane of rotation. the magnitude of the rod's angular momentum about its rotation axis, is 14.95 kg m2/s.
1. choose the correct direction of the angular momentum vector for the situation described above
a. fixed in the plane of rotation
b. along the length of the rod and rotating with it
c. none of the other choices
d. up
e. down
2. A thin-walled hollow sphere of radius 0.64 m and mass 1.4 kg rotates about a vertical axis through its center. The sphere makes one rotation every 0.39 second and rotates counterclockwise as viewed looking down from above. the magnitude of the sphere's angular momentum about its rotation axis, is 6.15 kg m /s.
choose the correct direction of the angular momentum for the situation described above
a. fixed in a horizontal direction
b. none of the other choices
