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.
