Question

an object takes 0.35 seconds to hit the floor, what height did it fall from?

is the way to calculate it

h = gt^2 / 2

so would it be =

h = .5 * 9.8 * 0.35^2

Answer 1

yes that's correct

just don't forget that your answer is in meters, since you used 9.8

many teachers will count off if you don't include units in your answer
