Physics 3710 – Problem Set #2 Newtonian relativity
Problems 1-4 refer to: Sound travels at about 330 m/s in still air. Observer O is at rest with respect to still air, observer O′ travels with constant velocity +50 m/s in the common x, x′ direction. Event A is the emission of a sound pulse from a stationary source at the origin of O; it occurs at xA = 0 at tA = 0. Event B is the reflection of the pulse at xB = +100 m. Event C is the detection of the reflected pulse at x …

Physics 3710 – Problem Set #5 Relativistic dynamics, I
Problems 1-5 refer to: One mass, m1 = 1 (in some units), collides head-on with a second mass, m2 = 2 , and sticks to it, forming a composite body of mass M . There are no external forces. Observer O records m1 as initially moving with dimensionless velocity, u1 = +0.9 in the x - direction, while m2 is recorded to be at rest. Do not make unwarranted assumptions about M , please; that’s the point of this set of problems.
