a) how long does it take to fall the first 50m?

b)How long does it take to fall the last 50m?

Which equation would I use to solve this problems with?

For a) use s=(1/)g*t^2 where s=50m and g=9.8m/s^2 and solve for t.

For b)use s=(1/)g*t^2 where s=1000m and g=9.8m/s^2, solve for t and subtract the result of part a).

You use the same formula, but you look at the total time minus some partial time. Does that make sense?
