1) The buoyant force acting on an object immersed in a fluid is:
where
is the density of the fluid, 
is the volume of displaced fluid, and 
is the gravitational acceleration.
2) We must calculate the volume of displaced fluid. Since the titanium object is completely immersed in the fluid (air), this volume corresponds to the volume of 1 Kg of titanium, whose density is
. Using the relationship between density, volume and mass, we find
3) Now we can recall the formula written at step 1) and calculate the buoyant force. The air density is
, so we have
4) The weight of 1 Kg of titanium is instead:
So, the buoyant force is negligible compared to the weight.

Answer:
Explanation:
As we know Newton's II law
= Rate of change in momentum
so we will have
now we will have
so here we can say that change in momentum of the object is the product of force and interval of time for which the force is acting on it.
so we will have
