Question

consider the following equation of motion and rewrite them for a free fall body v=u+at s=ut+1/2at square

Answer 1

hi friend
here is your answer

for a free fall body
at initially it was at rest (u=0)
and the only acceleration is the gravity (a=g)
So the new equation is
v=gt
s=1/2 g t^2

but sometimes happens that u≠0 as calculation is from between of fall.
so if this is the case you will just replace a with g
so the equation will be
v= u + g t
s=u t + 1/2 g t^2


hope this helps
