Two books are resting side by side, in contact, on a desk. A 0.58 N horizontal force causes the books to move together with an acceleration of 0.21 m/s2 horizontally. The mass of the book to which the force is applied directly is 1.0 kg. Neglecting friction, determine a) the mass of the other books b)the magnitude of the force exerted by one book on the other.

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?
