show that linear combination of e^ikx and e^-ikx is a eigen function of d²/dx²

if known psi(x)=(2-i)e^3ix determine |psi(x)|²

1. The force required to draw back the string of an archers bow by a distance 'x' from it equilibrium position is given by f=kx2 if all the energy stored in the bow is communicated to the arrow, show that the maximum range of the arrow is given by R=2kx2/3mg

A rocket fires two engines simultaneously. One produces a thrust

of 725 N directly forward while the other gives a 513 N thrust at

32.4 o above the forward direction. Find the magnitude and direction (

relative to the forward direction) of the resultant force which these

engines exert on the rocket.
