How far will a freely falling object fall from rest in six seconds?

Accepted Answer

Here are two ways to do it:Way #1:-- You know that gravity accelerates things that are falling freely, adding 9.8 m/s to their speed every second.-- After 6 seconds, an object that fell from rest winds up falling at (9.8 x 6) = 58.8m/s.-- During that time, its average speed was 1/2(0 + 58.8) = 29.4 m/s .-- In 6 seconds, at an average speed of 29.4 m/s, it covers (29.4 x 6) = 176.4meters.Way #2:This way only works if you remember the formula for the distance covered during uniform acceleration.             D  =  1/2 (acceleration) (time)²Acceleration = gravity = 9.8 m/s²Time  =  6 seconds           D  =  1/2 (9.8) (6)²  =  176.4 meters.

Tabulate, then find the proper equation, then solve.vi=0vf=?t=6sa=g=9.8m/s²vf=vi+atvf=gtvf= (find this yourself)
