Since particle is atsame height at time t1&t2, therefore,t1 + t2 = total time of flightt1 + t2 =2TT=t1+t2/2AlsoT=u/g from (v=u+at and v being 0 at maximum height and g is negative)Therefore u/g=T1+t2/2Or U=1/2g(t1+t2)

Since particle is at same height at time t1&t2,

Therefore,

(t1 + t2)= total time of flight

(t1 + t2) =2T

T=(t1+t2)/2

AlsoT=u/g from (v=u+at and v being 0 at maximum height and g is negative)

Therefore,

u/g=(t1+t2)/2

u=g(t1+t2)/2

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.
