Answer:

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

[tex]s = ut+\dfrac{1}{2}gt^2[/tex]

Where, s = height

u = initial velocity

g = acceleration due to gravity

t = time

Put the value in the equation

[tex]s = 0+\dfrac{1}{2}\times9.8\times2^2[/tex]

[tex]s = 19.6\ approx\ 20\ m[/tex]

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