The scientific knowledge was necessary for Schrödinger’s work is the discoverd of electron.
<h3>What is electron and how was it discovered?</h3>
Thomson carried out new experiments that led him to conclude that cathode rays were formed by particles that have a negative charge. Later, Thomson proved that these rays were deflected by applying an electric field. Thus, these particles were called electrons.
The discovery of the electron allowed Schrodinger to explain quantum models that are based on how electrons behave.

There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
Answer:
![\boxed {\boxed {\sf 252.5 \ Newtons }}](https://tex.z-dn.net/?f=%5Cboxed%20%7B%5Cboxed%20%7B%5Csf%20252.5%20%5C%20Newtons%20%7D%7D)
Explanation:
Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.
![F=m*a](https://tex.z-dn.net/?f=F%3Dm%2Aa)
The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:
Substitute the values into the formula.
![F= 50.5 \ kg * 5.0 \ m/s^2](https://tex.z-dn.net/?f=F%3D%2050.5%20%5C%20kg%20%2A%205.0%20%5C%20m%2Fs%5E2)
Multiply.
![F=252.5 \ kg*m/s^2](https://tex.z-dn.net/?f=F%3D252.5%20%5C%20kg%2Am%2Fs%5E2)
- 1 kilogram meter per square second is equal to 1 Newton.
- Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.
![F= 252.5 \ N](https://tex.z-dn.net/?f=F%3D%20252.5%20%5C%20N)
The force required is <u>252.5 Newtons</u>.
