The distance h a body will move in a free fall is expressed by the formula h = 1/2 gt 2. if g = 980 cm per sec per sec and t = 20 sec, the distance h is a. 368,000 cm. b. 49,000 cm. c. 196,000 cm. d. 9,800 cm.

The correct option is D. The distance h is 196000 cm.

Step-by-step explanation:

The given formula is,

Where, g is the gravitational acceleration,

t is the time in second,

Here, g = 980 cm per sec and t = 20 seconds,

Therefore,

Thus, the required height = 196000 cm

Therefore option D is correct.
