two particles are throewn from a certain height0along horizontal direction mutually opposite to each other with velocities V1 AND V2.
find the distance between the particles when velocity vector becomess mutually perpendicular.
let 't' be time. velocity vectors are v1(t) =V1ti+gtj,and v2(t)= -V2ti+gtj
when velocity vector is mutually perpendicular at t=tp, v1(tp)·v2(tp)=0
let h be initial horizontal distance
at tp distance=ltp(V1+V2)-hl
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
