Reason 1) A velocity vs. time plot of the motion would cross the time axis at the apex of its trajectory indicating a velocity of zero; if the velocity was never zero then a discontinuity would exist, i.e. the object would suddenly jump from one velocity to another with no intervening motion, that just seems way too unphysics like in this universe.
Reason 2) Finding the velocity as the limit of the time approaches zero would imply zero divided by zero which equals zero:
vinstantaneous = (lim x:0) ∆x/(lim t:0)∆t
= 0/0 (units)
=0 (units)

What kind of energy does a ball have when thrown straight up at the peak of the arc?
At the peak of its arc, the ball has potential energy due to its position in the gravitational field. Its kinetic energy is momentarily zero because it has come to a stop before descending.
What is parabolic arc trajectory?
A parabolic arc trajectory is the curved path that an object follows when thrown or launched into the air, under the influence of gravity. This type of trajectory is characterized by a symmetric shape resembling a parabola, with the object reaching its highest point midway through its flight path. Projectile motion, such as that of a thrown ball or a launched rocket, often follows a parabolic arc trajectory.
What happens when you stop pushing someone on a swing?
When you stop pushing someone on a swing, the swing will gradually slow down due to the forces of friction and air resistance acting on it. Eventually, the swing will come to a stop at the lowest point of its arc. The person on the swing will feel the deceleration and will likely have to start pumping their legs to keep the swing in motion.
What measures the length of the path that an object follows during its motion?
The measure that quantifies the total distance traveled by an object during its motion is known as the "path length" or "arc length." This distance is calculated by integrating the magnitude of the velocity vector along the path traveled by the object.
How does a capatult work?
A catapult works by using tension stored in flexible materials like wood or rope to launch an object. When the tension is released, the stored energy is transferred to the object, propelling it forward. The object is launched in a high arc due to the design of the catapult's arm and the force applied.
What is the small-angle formula?
The small angle formula is used for measuring the distance to a far away object when the actual size and angular size are known, or for finding out the actual size of a faraway object when the distance to the object and angular size are known. In arc-seconds: a = 206265 x D/d where a = the angular size of the object in arc-seconds D = the actual linear size of an object in km d = the distance to the object in km 206265 = the number of arc-seconds in a complete circle divided by 2pi In Radians: a = D/d where a = angular size of object in radians
Does a semicircle have an arc measure of 360 degrees?
The complete arc of a semicircle is 180 degrees
What is another word for not complete?
incomplete
Which comes first bounto arc or arrancar arc?
The Bounto arc (episodes 64-109) comes before the Arrancar arc (episodes 110 to the 300s) which is not yet complete
What is the number of degrees in an arc of a circle?
It depends on the length of the arc because there are a total of 360 degrees in a complete circle.
What town did Joan of Arc come from?
What "town" did Joan of Arc come from? She was born in Domremy and lived there until she was sixteen when she left for good.
When this construction is complete the angles that intersect arc 1 and arc 2 are because they are angles.?
They are congruent because they are supplemental angles
When this construction is complete the angles that intersect arc 1 and arc 2 are because they are angles?

What kind of energy does a ball have when thrown straight up at the peak of the arc?
At the peak of its arc, the ball has potential energy due to its position in the gravitational field. Its kinetic energy is momentarily zero because it has come to a stop before descending.
What does the wedding arc on the tribez do?
The wedding arc gives you ten experience for 30 coins. You will need to build it to complete certain tasks.
Who fought the English but was later burnt at the stake?
Joan of Arc come to mind (Jeanne D'Arc)
How did Joan of Arc stop the 100 Year's War?
Joan of Arc did not stop the 100 Years War, however her actions acted as the turning point in the war that eventually allowed the French to win.
