The terrain is level and that the air drag is negligible : A shell is shot with an initial velocity v1 of 33 m/s, at an angle of 60° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass (Fig. 8-26). One fragment, whose speed immediately after the explosion is..

Frequency of small oscillations about equilibrium position : A rod of length l and mass m, pivoted at one end, is held by a spring at its midpoint and a spring at its far end, both pulling in opposite directions. The springs have spring constant k, and at equilibrium their pull is perpendicular to the rod. ..
