Relative velocity of jeep wrt culprit=v =108-90=18km/h

=5m/s

Relative acceleration =-2m/s

Relative distance =-300

Let they meet after time t

-300=5t-t²

t²-5t-300=0

t=20s

Distance covered by culprit in 20 sec=20*25

=500m

Hence they meet after 800m from point of start of jeep

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.
