From the difference in mass of a hydrogen atom (Appendix B) to the mass of a proton and an electron (Table 1.5), estimate the binding energy of the electron in the hydrogen atom. Compare this to the ionization energy of the ground state electron as calculated by the Bohr model. What fraction of the total mass is lost as the electron binds to the proton?
A runaway railroad car, with mass 30 x 10^4 kg, coasts across a level track at 1.5 m/s when it collides with a spring loaded bumper at the end of the track, What is the maximum displacement of the spring after the collision
A 144-g baseball moving 29m/s strikes a stationary 5.25-kg brick resting on small rollers so it moves without significant friction. Determine the baseball's speed after the collision
In the path shown below, the locations of a car driving around a track are shown at EQUAL time intervals where ?t = 20 s. The car starts with speed 40 m/s at x0 and uniformly slows down to 20 m/s from x0 to x2. The car then travels at a constant spee..
