A rifle bullet is fired horizontally off the top of an ocean-based drill site. If the air resistance is negligible and the vertical distance to the water is 35 m, what additional information is needed to determine the time required for the bullet ..
A thin film with index of refraction n = 1.29 is placed in one arm of a Michelson interferometer, perpendicular to the optical path. If this causes a shift of 8.0 bright fringes of the pattern produced by light of wavelength 693nm, what is the film t..
A 76 g, 40-{rm cm}-long rod hangs vertically on a frictionless, horizontal axle passing through its center. A 10 g ball of clay travelling horizontally at 2.70 m/s hits and sticks to the very bottom tip of the rod. To what maximum angle, measured fro..
