What is free fall?

When an object is thrown from a given height, the gravitational force causes it to descend towards the Earth's surface. Such a motion of an object is known as free fall.

We can an assume her that marble is project with horizontal velocity=2 neglect air resistance it falls a distance 1m it vertical velocity initially is 0.

Since ,

h= 1 ,  g=10

The formula for free fall:

h=1/2gt²

1 = 1/2*10*t²

t² = [tex]\frac{2}{10}[/tex] = 0.2s

t = 0.2236s

Therefore,

0.2236s will the marble be in the air.
