when the object reaches maximum height, the velocity of the object is 0 m/s.
It reaches maximum height when the gravity of the body has slowed its velocity to 0 m/s. If there is no gravity and there is no external force acting on it then it will never reach a maximum height as there wont be a negativeaccelerationdemonstrated by newtons first law.
Where there is and you have the objects initial velocity then you can use :
v^2 = u^2+2.a.s
v = Velocity when it reaches Max. height so v = 0
u = Initial Velocity (m/s)
a = Retardation/ Negative Acceleration due to gravity, -9.80m/s ^2
And then the unknown (s) is the displacement, or height above ground, and if everything else is in the right format it should be in metres.

What is the difference between fetch and catch?
Fetch means "go and bring back." Catch means "grab ball when thrown."
Dangling reference in java?
I think you're referring to the C/C++ concept of "dangling pointers." This is when you allocate some memory to a pointer, then deallocate that memory, but don't change the pointer. This causes any attempted use of the pointer to return an unused memory address. There is no such concept in Java, since the programmer has little to no control over how memory is allocated or freed. The closest thing I can think of is if you're using a class such as a Reader, in which you can close the object (Reader.close()) and then still have a reference to it. But in this case (and other similar cases) attempting to use the Reader further will result in an IOException being thrown.
How much is in a heap?
A heap is unspecified - it is a group of things placed, thrown or lying one on another. It can be a great quantity or a small number. It can refer to a 'heap' of food on a plate to a 'heap' of stone as in a hill. A similar word would be 'pile'
Who discovered irrational numbers?
Hippasus, However Pythagoras could not accept the existence of irrational numbers, because he believed that all numbers had perfect values. But he could not disprove Hippasus' "irrational numbers" and so Hippasus was thrown overboard and drowned.
Why does the speed dcreses when an object is thrown vertically up?
The speed decreases when an object is thrown vertically up because of the force of gravity acting against the object's upward motion. As the object goes higher, the force of gravity slows it down until the object reaches its maximum height, where its speed momentarily becomes zero before accelerating back downward.
What relationship exists between the initial velocity and the maximum height reached by an object thrown upward?
Ignoring air resistance, I get this formula:Maximum height of a vertically-launched object = 1.5 square of initial speed/GI could be wrong. In that case, the unused portion of my fee will be cheerfully refunded.
An object thrown vertically up wards from the ground returned back to the ground in 6s after it was thown up if it reached a height of 12m calculate?
An object thrown vertically up wards from the ground returned back to the ground in 6s after it was thown up if it reached a height of 12m calculate?
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.
What angle a projectile thrown to achieve maximum vertically distance traveled?
90
What is the velocity of an object thrown vertically into the air at its highest point?
At the highest point, the velocity of an object thrown vertically into the air is momentarily zero as it changes direction. This is the point where it transitions from going upward to downward.
How much work is done when an object is thrown upward?
When an object is thrown upward, work is done against gravity as the object moves upward. The amount of work done is equal to the force applied to lift the object multiplied by the distance it moves vertically.
What is the instantaneous velocity at maximum height when something is thrown straight up?
The instantaneous velocity at the maximum height is zero because the object momentarily stops moving before falling back down due to gravity.
What is the furthest distance an object has been thrown by a human vertically and horizontally?
Horizontally
Where does a ball has the greatest potential energy?
A ball has the greatest potential energy at its highest point, such as when it is held at the top of a hill or at its maximum height when thrown vertically upwards. This is because the gravitational force acting on the ball is at its maximum, giving it the highest potential energy.
How would you estimate the maximum height you could throw a ball vertically upward?
To estimate the maximum height a ball could be thrown, you would need to consider factors like the initial velocity of the throw, the angle at which the ball is released, and the force of gravity. Using kinematic equations, you can calculate the height based on these factors. Keep in mind that air resistance and other external factors may affect the actual height achieved.
How can a ball thrown vertically have the same time flight as a ball thrown at an angle when they have the same maximum height?
They might seem like they have the same flight patterns, but they don't. A 12-6 curveball thrown by an over-hander will go from 12 to 6, but if the same is thrown by a 3/4 or side-armer, the ball will react a little more like a slider.
