If you balance a broom horizontally on one finger, the center of gravity of the broom will be above your finger – closer to the bristles end than the handle end. if you saw the broom in two pieces at that point and weigh the two parts on a scale, you'll find that the heavier part is

the bristles part
the handle part
both the same weight

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?

An owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?
