Use the average time to drop and calculate the distance dropped using the equation given.  Then compare this distance to the measured distance.  Use Y = 1/2 g t^2, Thus Y= 4.9 t^2

See my attempt attached with the data - teacher indicated my work needed correction, please help

Thank you!

You will drop one of the hex nuts from a height of about 6 ft. Stand near a
wall, door jam, post of some kind and place a tape or have some other
way of marking the height you will drop the hex nut from. Record this
height.
With a stopwatch time the drop of the hex nut and record in the data table
below. Repeat this for a total of 10 trials.
Height of Drop: 6FT

Using the average time from the table calculate the distance the hex nut
dropped and compare to your recorded distance. y = 1/2* g * t^2
where y is the distance dropped, g is the gravitational acceleration (about 9.8
m/s2), and t is the time taken. Let's start by converting 6 feet to meters. Because
1-foot equals 0.3048 meters, the height in meters is:
6 feet tall * 0.3048 meters/foot = 1.8288 meters
We can now determine the distance dropped:
y = 1/2* (9.8 m/s^2) * (0.642 s) ^2
y≈ 1/2 * 9.8* 0.412164 y≈
2.02074 meters
