A train of length l=350m starts moving rectilinearly with constant acceleration w=3.0⋅10-2m/s2, t=30s after the start the locomotive headlight is switched on (event 1), and τ=60s after that event the tail signal light is switched on (event 2). Find the distance between these events in the reference frames fixed to be train and to the Earth. How and at what constant velocity V relative to the Earth must a certain reference frame K move for the two events to occur in it at the same point?

Two simple pendulums of length 0.5 m and 20 m respectively are given small linear displacement in one direction at the same time. They will again be in the phase when the pendulum of shorter length has completed oscillations When an oscillator completes 100 oscillations its amplitude reduces to 1\3 of its initial value. What [...]
