Dear Student,
Given a vector as:
a=2i+2xj
x=2 X 9/2= 9
Vx=√(2X2X9)
=6m/s
∫VydV= ∫aydx
=>v2/2|(from 0 to v)=x2|(from 0 to 9)
=>Vy= 9√2
V=6i+9√2j
Cheers!!

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.
