potential energy = m*g*h m=62kg g=9.81 m/s^2 h=410m multiply all those together and you get 249,370 Joules.

What is the total momentum of cannon and shell before and after firing?
Before the cannon is fired, the momentum is zero. So, after firing, the momentum must still be zero. The momentum of the shell is equal and opposite to that of the cannon, because there is an action and an equal reaction force. Since the momentum difference must be equal: (mv)cannon = (mv)shell Thus, (mv)c - (mv)s = 0 A simple way of looking at it is this is: If the shell is 100 times lighter than the cannon then the shell will move off 100 times faster than the cannon recoils. Remember that, in explosions, the lighter portion moves off faster than the heavier one.
Electrons exist only at fixed levels of potential energy However if an atom absorbs sufficient energy a possible result is that?
An electron may move to an electron shell farther out from the nucleus.
Can an object have both potential and kinetic energy?
1 yes when electron moving in a shell 2 aeroplanes when moving in skies 3 when we are travelling in a bus or car
What is the energy level within a shell?
electrons are found in pairs
What is the momentum of a 35 kg shell fired from a cannon with a velocity of 500 m per s?
Momentum=35*500=17500Ns
Does an electron in the first energy shell have greater potential energy than an electron in the third energy shell?
electrons in the first electron shell have the lowest possible potential energy because YOUR MOM DROPPED U ON YOUR HEAD WHEN U WERE A BABY
Is potential energy in k-shell is negative then why?
bcoz the energy of bound system is always negative
What is a breech of a cannon?
the cannon breach is where the artillery shell is inserted for firing...................
What is a 90mm cannon shell worth?
The value of a 90mm cannon shell varies by its condition. As of 2014 these shells sell at auction for around 50.00.

When a shell explodes the fragments fly apart through no external force is acting on it does it violates newtuns law?
The source of the explosion comes from the stored chemical potential energy within the shell. However, the laws of physics still apply to this situation. Energy will be conserved: the sum of the chemical energy released by the explosive and the kinetic energy of the shell before the explosion will always equal sum of the combined kinetic energy of the fragments and the heat, sound, and light energy released by the explosion. Momentum will be conserved: the added momentum vectors of all the shell fragments will equal the momentum of the shell before it exploded. The shell fragments will not all travel in the same direction.

How do you spell shell in French?
a shell is une coquille, un coquillage (sea shell), une écaille (turtle), un obus (ammunition for a cannon)
Where is the shell that has the lowest energy level?
This electron shell is near the atomic nucleus.
What are artillery explosions?
An Artillery piece (large cannon) or gun firing a large calibre shell. When the shell landed this would be an artillery explosion.
Why Ionization potential decrease from top to bottom in s block element?
As from top to bottom on a periodic table one energy shell is added. Thus the distance between the electrons and the protons increase and the attraction force decreases. Then it becomes easier to get one electron out from the most outer shell. This is why the ionization potential decreases.
If electrons have the most energy in an atom electrons in an electron cloud electrons in the outermost electron shell electrons in the innermost electron shell electrons in the nucleus?
Electrons in the outermost energy shell (valence shell) have the most energy.
