Aball dropped from the roof of a tall building will fall approximately how far in two seconds? (a) 10 m, (b) 20 m, (c) 30 m, (d) 40 m, (e) 50 m.

The ball covered the distance in 2 second is 20 m.

(b) is correct option.

Explanation:

Given that,

Time = 2 sec

Using equation of motion

Where, s = height

u = initial velocity

g = acceleration due to gravity

t = time

Put the value in the equation

Hence, The ball covered the distance in 2 second is 20 m.
