H = 2.7 (above the ground)
Ux= v (velocity in circular path)
ay = -g
for horizontal motion threre is no accleration so ax =0
for verticle motion ,
S = gt2/2
2.7 = gt2/2
t = 0.74sec
now for horizontal motion
speed = distance/time
Ux = 10/(0.74) (distance 10m (given))
Ux = 13.51m/s
with this velocity particle was circulating .....
ac(centripital accleration) = v2/r = (13.51)2/1.5 = 122 m/s2

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.
