Physics 2203 Homework 2: Problems and Solutions, Assignments of Physics

Download Physics 2203 Homework 2: Problems and Solutions and more Assignments Physics in PDF only on Docsity! Phys 2203 Homework 2, due Wednesday September 12. The homework consists of a mix of problems from the textbook (at the back of each chapter), and some extra problems typed out below: (1) Problem 2.32 (left over from last week) (2) Problem 2.41 (3) Problem 2.60 (4) Problem 2.65 (be careful with precision here, both velocities are VERY close to c). (5) Problem 2.68 (6) A proton has a kinetic energy which is twice its rest energy (a) Calculate the speed of the proton (b) Calculate the momentum of the proton (in units of eV/c) (7) Problem 2.74. To find the numerical answer to this problem (v/c = 0.116) you have to do a bit of algebra at the end. Even if you don’t complete the calculations, the numerical value of the answer is good to remember for future estimates. (8) Problem 2.80 (9) An unstable particle has a mass M = 3.34 x 10-27 kg and is at rest. It decays into two fragments with velocities v1 = 0.987c and v2 = -0.868c respectively. Find the rest masses m1 and m2 of these fragments. (10) Problem 3.3 (11) Problem 3.9
