When the speed of a moving object is doubled its KE increased to 4 times how plz explain
1 Answer
Kenny Toijam
Just apply KE=1/2 mv^2............... putting v=2v......the new KE becomes KE=1/2m(2v)^2= 1/2m*4v^2= 4KE

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.
