Question

For freely falling object we can write the Newton’s second equation of motion as …

Answer 1

s = at^2/2

This can be written

Answer 2

Hey dear,

● Newton's second kinematics eqn -
Generally, Newton's second equation of motion is given by -
s = ut + 1/2 at^2

For freely falling body, s = h, u = 0, a = g, thus
h = o×t + 1/2 g×t^2
h = 1/2 gt^2

Therefore, Newton's second equation of motion for freely falling body is h = 1/2 gt^2 .

Hope this helps you...
