a car travels half distance with speed 60km/h and rest with 30km/h then avg. speed is
1 Answer
Abhinav
let total distance be 2D
than total time taken is D/30 + D/60
hence avg speed is 40km/h
than total time taken is D/30 + D/60
hence avg speed is 40km/h

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.
