Answer:
The correct option is D. The distance h is 196000 cm.
Step-by-step explanation:
The given formula is,
[tex]h=\frac{1}{2}gt^2[/tex]
Where, g is the gravitational acceleration,
t is the time in second,
Here, g = 980 cm per sec and t = 20 seconds,
Therefore, [tex]h = \frac{1}{2} \times 980(20)^2=490\times 400=196000[/tex]
Thus, the required height = 196000 cm
Therefore option D is correct.
