A spring of negligible mass and force constant k = 500 N/m is hung vertically, and a 0.300 kg pan is suspended from its lower end. A butcher drops a 1.5 kg steak onto the pan from the height of 0.30 m. The steak makes a totally inelastic collision with the pan and sets the system into vertical SHM. What are a) the speed of the pan and steak immediately after the collision; b) the amplitude and the period of the subsequent motion?

Suppose you were asked to find the torque about point p due to the normal force n in terms of given quantities. which method of finding the torque would be the easiest to use?

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

With the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 1.90
