Find the momentum and kinetic energy
An electron and a proton are each accelerated through a potential difference of 21 million volts. Find the momentum (in MeV/c) and kinetic energy of each, and compare with the results when using the classical formulae.

Suppose that from t = 0 to t = 4.9 s, the elevator ascends at a constant speed of 10 m/s. Its speed is then steadily reduced to zero during the next 3.2 s, so that it is at rest at t = 8.1 s. Describe the reading of the scale during the interval 0
