Answer:
d = 329.81m
Explanation:
V_f = V_0+a*t
V_f = Velocity final
V_0 = Velocity initial
a = acceleration
t = time
V_f = (0m/s)+(9.81m/s²)*(8.2s)
V_f = 80.442m/s
d = ((V_f-V_0)/2)*t
d = distance
d = ((80.442m/s-0m/s)/2)*(8.2s)
d = 329.81m

The image distance is 59.2 cm and the image is real and small.
<h3>
Image distance</h3>
The distance of the image formed by the convex or converging lens is determined by applying the following lens equation.
1/f = 1/u + 1/v
where;
- f is the focal length = 34 cm
- u is the object distance = 80 cm
- v is the image distance = ?
1/v = 1/f - 1/u
1/v = 1/34 - 1/80
1/v = 0.0294 - 0.0125
1/v = 0.0169
v = 1/0.0169
v = 59.2 cm
Thus, the image distance is 59.2 cm and the image is real and small.
