A particle is dropped along the axis from a height `(f)/(2)` on a concave mirror of focal length f as shown in figure. Find the maximum speed of image .

A particle is dropped along the axis from a height f/2 on a concave mirror of focal length f as shown in the figure. The acceleration due to gravity is g. Then the maximum speed of the image is given by 3/4sqrt(x f g) where x=………...
