A thin stick of mass 0.5 kg and length
L = 0.8 m
is attached to the rim of a metal disk of mass
M = 5.0 kg
and radius
R = 0.4 m.
The stick is free to rotate around a horizontal axis through its
other end (see the following figure).
(a)
If the combination is released with the stick horizontal, what
is the speed (in m/s) of the center of the disk when the stick is
vertical?
m/s...
1. If a rod travels with a speed v 0.8 c along its length, how much does it shrink? 2. Assuming that the rest radius of earth is 6,400 km and its orbital speed about the sun is 30 km, how much does earth's diameter appear to be shortened to an observer on the sun, due to earth's orbital motion? 3. A rod of length Lo moves with speed v along the horizontal direction. The rod makes and angle 0o...
