A super-ball of mass m is to bounce elastically back and forth between two rigid walls at a distance d from each other. Neglecting gravity and assuming the velocity of super-ball to be `v_(0)` horizontally, the average force being exerted by the super-ball on each wall is

Options

B. `(mv_(0)^(2))/(d)`
C. `(2mv_(0)^(2))/(d)`
D. `(4mv_(0)^(2))/(d)`

Answer

B
