In a 400-m relay race the anchorman (the person who runs the last 100 m) for team a can run 100 m in 9.8 s. his rival, the anchorman for team b, can cover 100 m in 10.1 s. what is the largest lead the team b runner can have when the team a runner starts the final leg of the race, in order that the team a runner not lose the race?

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?
