Question

Two stones of mass 10g and 1kg are dropped from same height on a glass table. Which stone will have more momentum and why?
​

Answer 1

✏✏because the mass is different but the velocity is equal 9.8m/s2

✏✏When we dropped down the stone at same time same velocity than they both will reach at the ground at same time.

✏✏Variation came only in change of gravity .

Answer 2

Answer:

F = ma , where

M- mass and A- acceleration

So here acceleration is due to gravity which remains same for all objects i.e. 9.8m/sec.

And mass is 10kg and 1 kg

So the net force pulling the stones will be

F — 98N (10kg stone) and

F — 9.8N (1kg stone)

Since more force is on 10kg stone thus it will reach the ground first .

If the buoyancy , air drag and net aerodynamic resistance remain same foe both the bodies

Only in one condition 1 kg stone will fall first if

The opposing force is more than 88.2N which includes buoyancy, aerodynamic resistance etc.
