physics kinematics two particles are simultaneously projected in opposite directions horizontally from a same point in space where g is constant. If u1 and u² are there initial velocities. then the time t after which the velocities are mutually perpendicular is given by

Dear student 
Two particles are projected in opposite direction 
So, let us assume it vectorily  
-4i -10tj 
9i - 10tj
-36 + 100t^2 = 0 
Find t from here 
t =0.06 sec 
Hope this helps 
Good luck
