Answer:

21.8 m/s

Step-by-step explanation:

Given that Tom drops a object from a height of <em>h </em>meters and it hits the ground with a veloc8of <em>v </em><em>m/</em><em>s </em>and it is given by function ;

\longrightarrow v =\sqrt{19.6h}

We need to find out the velocity upon reaching the ground when it is dropped from a height of 24.3 m . On plugging in 24.3 in place of h we have ,

\longrightarrow v =\sqrt{19.6\times 24.3 }\ m/s\\\\\longrightarrow v =\sqrt{ 476.28} m/s \\\\\longrightarrow v = 21.823 \ m/s \\\\\longrightarrow \underline{\underline{ v = 21.8 \ m/s }}

And we are done !

Answer:

<u>21.8</u>

Step-by-step explanation:

The formula is given :

  • v = √(19.6h)

Given that h = 24.3 m, we need to find v.

Substituting the value of h in the formula :

  • v = √(19.6)(24.3)
  • v = √476.28
  • v = <u>21.8</u> m/s (nearest tenth)
