Answer:

7.475 seconds pass before the object makes a splash

Explanation:

The time it takes for a dropped object to fall and hit the ground can be determined using the kinematic equation.

h=1/2gt^2

h is the height (in meters),

g is the acceleration due to gravity (approximately 9.8 m/s^2 ),

t is the time (in seconds).

h=274

g = 9.8m/s^2

Then rewrite the problem as:

[tex]T=\frac{2*h}{g}[/tex]

Plug in Values

[tex]T=\frac{2*274}{9.8}[/tex]

Solve

[tex]T= \sqrt{\frac{548}{9.8}}[/tex]

Calculate

[tex]T=\sqrt{55.918}[/tex]

T=7.475 seconds

Approximately 7.475 seconds pass before the object makes a splash.
