A very light rod with a length of 1.95m extends straight out fromone end of a meter stick. The other end of the rod serves as apivot and the system is set into oscillation
a) determine the period of oscillationb) By what percent does the period differ from the period of asimple pendulum 2.45m long
Hint: use theory of parallel axis
The Beretta Model 92S (the standard-issue U.S. army pistol) has a barrel 127 long. What is the acceleration of the bullet while it is in the barrel
Illustrate what is the magnitude of the change in momentum of the ball while in contact with the bat if the ball leaves with a velocity of (a) 18 m/s, vertically downward, and (b) 18 m/s, horizontally back toward the pitcher?
Honeybees acquire a positive charge while flying through the air. The rapid motion of the wings through the air provides the "friction" to strip charges off the bee, find the strength of the electrostatic force on the pollen grain
