-By Newton's second law:
where is the displacement from equilibrium position. The equation can be transformed into:
shich is the equation of motion.
The De Broglie wavelength of the electron is
And we can use De Broglie's relationship to find its momentum:
Given
, with m being the electron mass and v its velocity, we can find the electron's velocity:
This velocity is quite small compared to the speed of light, so the electron is non-relativistic and we can find its kinetic energy by using the non-relativistic formula:

Answer:
a
The speed is
b
The distance is
Explanation:
From the question we are told that
The speed of the banana is
The distance from my location is
The time taken is
The speed of the ice cream is
substituting values
The distance of separation between i and Valdimir is the same as the distance covered by the banana
So
substituting values
