1 Answer
Shailendra Kumar Sharma
So the stone is falling from 40m above the windowTo find out time S=ut+1/2(gt^2)So 40= 1/2(9.8t^2) thus T= 2.85 second

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.
