Two particles A and B move from rest along a straight line with constant accelerations f and h respectively. If A takes m seconds more than B and describes n units more than that of B acquiring the same speed, then

A

`(f+h)m^(2) = f h n`

B

`(f-f h)m^(2) = f h n`

C

`(h-f)n = (1)/(2)f h m^(2)`

D

`(1)/(2)(f+h)n = f h m^(2)`
