Sagot :

The velocity of the stone when it hits the water, i.e., the final velocity of the stone, v=68.6 m/s

The acceleration of the stone, a=9.8 m/s²

As the stone was dropped (not thrown), the initial velocity of the stone, u=0 m/s

From one of the equations of the motion,

[tex]v=u+at[/tex]

Where t is the time interval in which the stone hits the water.

On rearranging the above equation,

[tex]t=\frac{v-u}{a}[/tex]

On substituting the known values in the above equation,

[tex]\begin{gathered} t=\frac{68.6-0}{98} \\ =0.7\text{ s} \end{gathered}[/tex]

Therefore the stone hits the water 0.7 seconds after it is dropped.
