The answer is D. 32 m.
The simple equation that connects speed (v), time (t), and distance (d) can be expressed as:
⇒ 
It is given:
t = 10 s
d = ?
So:
The simple equation that connects speed (v), time (t), and distance (d) can be expressed as:
It is given:
t = 10 s
d = ?
So:
Formula for final velocity: Vf= vi+(a*t)
Vi- initial velocity, a=acceleration, t-time
Vf=vi+(at)
Vf= 0+(9.8m/s*2.8s)
Vf= 27.44 m/s
The acceleration of the Earth when dropping something would be 9.8 m/s
