Two particles move in a uniform gravitational field with an acceleration g. At the intial moment the particles were located at one point and moved with velocity `v_(1)=1" "ms^(-1)" and "v_(2)=4" "ms^(-1)` horizontally in opposite directions. Find the time interval after their velocity vectors become mutually perpendicular
