Detailed Solution

The vertical distance traveled by the projectile in

2

seconds is

19.6 m

Time taken for the stone to reach the ground

t =

2 s
Acceleration due to gravity

g = 9.8 m s^{- 2}

We are asked to find the vertical distance traveled by the projectile in

2

seconds. Once it starts its horizontal motion, the velocity turns zero at a particular distance of its horizontal direction. Once the velocity becomes zero the projectile will start falling down under the influence of gravity.so we can consider that the vertical motion of the projectile starts with initial velocity zero
Initial velocity of the projectile

u = 0 m s^{- 1}

We know that

S = ut + \frac{1}{2} a t^{2}

Here

a = g

Here we can write the above equation as

S = ut + \frac{1}{2} g t^{2} - - - - (i)

Substituting all the values in the equation (i)
We get

S = 0 \times 2 + \frac{1}{2} \times 9.8 {\times (2)}^{2}

= > S = 0 + \frac{39.2}{2}

= > S = 19.6 m

Thus the vertical distance traveled by the projectile in

2

seconds is

19.6 m
