An object falling through a fluid is observed to have an acceleration given by a=g-bv where g is the gravitational acceleration and b is a constant. After a long time it is observed to fall with a constant velocity. What would be the value of this constant velocity?

Explanation

Acceleration , a=g-bv when moving with constant velocity , a=0 `implies `0= g-bv
`therefore` Constant velocity, `v=g/bm//sec`
