Physics help please!!!!!!!!?

Question

how do you determine how far an object fell if you are only given the time it fell in?

Answer 1

distance=Vo+1/2gt^2

Since Vo=O

Distance=1/2gt^2

where g=acceleration due to gravity

          t=time

Answer 2

IN THE SIXTEENTH CENTURY Sir Isaac Newton give several equation regarding equation of a object.

By the third equation of motion

        

  s     =  ut   + 1/2at^2

s=distance covered

u=initial velocity

a= acceleration

##**##**##**##**##

we can calculate how much distance it cover

by equation of parabolic motions

  horizontal range, R=[2u^2sin(theta)cos(theta)]/g

where ,

**u=initial velocity

**(theta)=angel of projection with horizontal direction

   It will help to impress your teaches and collegues that if you project  an object at 45 degrees it will cover the max distance.

Nice to help such curious little scientists.
