Dear student

Since the velocity is horizontal

Vertical velocity can be assumed to be 0

Time required to reach ground is (2*45/g)^0.5 = 3 sec

Now horizontal dist = 10*3 = 30 meters

The answer would be 30 m as ....

the time taken by the ball toreach the drowns is 3 second by half at square =45

so 3*10= 30............................ Answer

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.
