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

Two particles move in a uniform gravitational field with an acceleration g .At the initial moment the particles were located at same point and moved with velocities u_(1)=9 ms^(-1) and u_(2)=4 ms^(-1) horizontally in opposite directions.The time between the particles at the moment when their velocity vectors are mutually perpendicular in s in (take g=10 ms^(-2) )

Two particles move in a uniform gravitational field with an acceleration g. At the initial moment the particles were located over a tower at one point and moved with velocities v_1 = 3m//s and v_2= 4m//s horizontally in opposite directions. Find the distance between the particles at the moment when their velocity vectors become mutually perpendicular.

Two particle move in a unifrom gravitational field with an acceleration "g". At the initial moment the paricles were located at one point and moved with velcoities u_(1) = 3.0 ms^(-1) and u_(2) = 4.0 ms^(-1) horizontally in opposite directions. Find the distance between the patricles at the moment when their their velocity vectors become mutually perpendicular .
