Answer:
The ball takes 
to hit the ground.
Explanation:
• The second equation of motion represents the total distances travelled by an object in a time interval of 
with an initial speed of 
and acceleration 
.
• To find the time, ball takes to hit the ground, use the formula: 
Where, 
is time, is initial velocity, is acceleration and
is displacement.
• In this case, 
.
• Placing the value of the given initial velocity, 
and displacement,
in the above formula.

Meters
The metre is a unit of length in the metric system, and is the base unit of length in the International System of Units (SI).
As the base unit of length in the SI and other m.k.s. systems (based around metres, kilograms and seconds) the metres is used to help derive other units of measurement such as the newton, for force.
When you're in an airplane that's 7 miles up off the ground, the strength of gravity plunges to only 99.6 percent of its strength all the way down on the ground.
A big heavy person, who weighs 200 pounds down at the airport, weighs only 199 pounds 4.7 ounces in a plane at the altitude of 7 miles.
