Suppose that 1000 pollen grains slam into the abdomen of a 5.0 g bee that is hovering just above the flower. the grain's mass is 1.0×10−7g. if the collision is inelastic, what is the bee's speed immediately afterward?

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
