Answer:
Approximately 
.
Assumption: the ball dropped with no initial velocity, and that the air resistance on this ball is negligible.
Explanation:
Assume the air resistance on the ball is negligible. Because of gravity, the ball should accelerate downwards at a constant 
near the surface of the earth.
For an object that is accelerating constantly,
,
where
is the initial velocity of the object,
is the final velocity of the object.
is its acceleration, and
is its displacement.
In this case, is the same as the change in the ball's height: 
. By assumption, this ball was dropped with no initial velocity. As a result, 
. Since the ball is accelerating due to gravity, 
.
.
In this case, would be the velocity of the ball just before it hits the ground. Solve for
.
.
Answer:
Some physicists believe in a flatter version of multiple universes. ... But if the universe began at a finite point, as nearly every physicist agrees that it did, an alternate version of you likely doesn't exist, according to astrophysicist Ethan Siegel's 2015 Medium article.
Just find the area of the graft
4m/s x 5s
=20m
Answer:
Explanation:
The equation for centripetal force is given by Newton's 2nd Law:
The equation for centripetal acceleration is 
If the object makes one revolution (an angle of 
) every 5 seconds it means that its angular velocity is 
.
Putting all together, and for our values:
Answer:
one hundred fifty thousand, six hundred twenty-four
