1. What is the momentum (p) of a 960-MeV proton (that is, its kinetic energy is 960 MeVMeV )? Express your answer with the appropriate units.

2. An electron (mmm = 9.11×10−31 kg ) is accelerated from rest to speed v by a conservative force. In this process, its potential energy decreases by 6.70×10−14 J . Determine the electron's speed, v. (in term of c.)
