The total displacement of the person walking from point A to point B is 300 yards.
As shown in the figure we can conclude that the required method to calculate the total displacement is the Pythagoras theorem.
<h3>Pythagoras theorem in brief :</h3>According to the Pythagorean Theorem, the square that represents the hypotenuse, or side of a right triangle that faces the right angle, is equal to the total of the squares on the triangle's legs.(or, in popular algebraic notation, ).
Let,
a = 500
b= 300
Hence by using Pythagoras' theorem
Total displacement of the person = =
=
Thus the total displacement of the person from starting point is 300 yards.

The correct expression for the maximum speed of the object during its motion is .
The maximum speed of the object is determined using the following formulas;
v(max) = Aω
where;
- A is the amplitude of the motion
- ω is angular speed
The maximum speed of the object can also be obtained from the maximum net force on the object,
F = ma
where;
- F is the maximum net force
- a is the acceleration
- m is mass of the object
F = m(v/t)
mv = Ft
v = Ft/m
Thus, the correct expression for the maximum speed of the object during its motion is .

The velocity at point B is 10 m/s with a pressure of 262500 Pa
<h3>Bernoulli equation</h3>
According to the continuity equation:
A₁V₁ = A₂V₂
Where A is the area and V is velocity, ρ = density of water = 1000 kg/m³
Hence:
4(5) = 2(V₂)
V₂ = 10 m/s
Using Bernoulli equation:
The velocity at point B is 10 m/s with a pressure of 262500 Pa
