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

 196000 cm

Step-by-step explanation:

Here, the given formula,

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
