In its approach to an airport runway, an airplane of mass 1.24 x 10^5 kg has a velocity of 75.5 m/s [11.1 degrees below the horizontal]. Determine the horizontal and vertical components of its momentum.

A nucleus, initially at rest, decays radioactivly, leaving a residual nucleus. In the process, it emits two paricles horizontally: an electron with momentum 9.0 x 10^-21 kg m/s [E] and a neutrino with momentum 4.8 x 10^-21 kg m/s [S]. In what direction do...
