    How Do You Solve for C1 and C2 in Damped Simple Harmonic Motion?

    I'm having trouble with this problem. I want to get it into a form with cos but I'm stumped. The solution for damped simple harmonic motion is given by x = (e^(-rt/2m))(C_1*e^(iw't)+C_2*e^(-iwt)) If x = Acos phi at t = 0, find the values of C_1 and C_2 to show that x'=(approx)...

    Solving Violations of Causality with U > c

    I'm having trouble working this problem. I don't know where to begin. Here's the problem: Let P and Q be any events, P causing Q via propagation of some signal. Let the speed of the signal, call it U, be greater than the speed of light c. In S, the time seperationg is given by delta_t and...

    What Happens in a Relativistic Elastic Collision with Equal Masses?

    I've done the bulk of this problem (part A) but I still can't figure the last bit (part B): "Consider an elastic head-on collision between a projectile with mass m_a, velocity (vector)v_a, energy E_a, and three-momentum (vector)p_a and a stationary target of mass m_b. (That the collision is...

    Newton's 2nd Law and Orbital Motion

    Here's the problem...unfortunately I don't remember much about orbital motion. I'm a bit stuck on where to begin. If somebody could give me a little advice on how to tackle this problem I would appreciate it. Recall that the magnetic force on a charge q moving with velocity v in a magnetic...

    Resolve Paradox: Relativistic Snake Cut or Unhurt?

    A relativistic snake, of proper length 100cm is traveling across a table at V = 0.6c. To tease the snake, a student holds two ends of a cleaver 100cm apart and plans to bounce them simultaneously on so that the left one lands just behind the snake's tail. The student reasons, "the snake is...
