A short fired at a moving train (u=30 km/h) at an angle θ= arc sin1/5 with the track enters a compartment of dimension a×b=12m×14m through a corner away form the engine and passes out through the diagonally opposite corner. Calculate the speed of the shot.

A train of length l=350m starts moving rectilinearly with constant acceleration w=3.0⋅10-2m/s2 B decides to overtake A before C does.What minimum acceleration of car B ia required to avoid an accident? both being 1 km car A is travelling with a speed of 36km/h.Two cars B and C approach car A in opposite directions with a speed of 54km/h each. At a certain instant when the distance AB=AC On a two lane road t=30s after the start the locomotive headlight is switched on (event 1)
