Answer:
displacement = 2 m west
Explanation:
The displacement of an object is a vector connecting the final point of the motion of the object to the initial point, and its magnitude is equal to the length of the vector. So the magnitude of the displacement is basically the distance (measured in a straight line) between the final point and the starting point.
In this problem, we have:
- initial position of the acorn: 0 m
- final position of the acorn: 2 m west
So, the displacement has a magnitude of
d = 2 m - 0 m = 2 m
And the direction is west, since the final position is west compared to the initial position.

Answer:
Ke=electron kinetic energy=
Explanation:
The electron has a mass of 
The speed of light in a vacuum is a universal constant with the value 299 792 458 m / s (186 282,397 miles / s), although it is usually close to 
Kinetic energy (K) is the energy associated with bodies that are in motion, depends on the mass and speed of the body and is calculated using the formula:
Equation(1)
K=kinetic energy (J)
m =mass of the body (kg)
v= speed of the body
for this problem We replace in the equation (1)
= electron mass
=Half the speed of light
=electron speed
We replace in the equation (1) :
The energy kinetic of the electron is 
Answer:
final position = 325 m
Explanation:
distance covered in 1 second = speed x time
= 355 m/s x 1 s
= 355 m
∴ final position = initial position + distance covered
= - 30 m + 355 m
= 325 m
