The net displacement of the object from t = 0s to t = 8s is 2 m.

The initial velocity of the object is 1 m/s.

The  final velocity of the object is 0 m/s.

The average velocity of the object from t = 0s to t = 8s is 0.25 m/s.

The distance traveled by the object in the first 8 seconds is 6 m.

<h3>What is the displacement of the object?</h3>

The displacement of the object is the change in the position of the object.

d = Δx

d = x(0) = x(8)

d = 2 m - 0 m = 2m

<h3>Initial velocity of the object</h3>

v = x/t

v = 2m / 2 s

v = 1 m/s

<h3>Final velocity of the object</h3>

v = x/t

v = 0/8 s = 0 m/s

<h3>Average velocity of the object</h3>

v(avg) = Δx/Δt = 2 m/8 s = 0.25 m/s

<h3>Distance traveled by the object in the first 8 seconds</h3>

in the first 2 seconds = 2 m

in the first 6 seconds = 4 m

in the first 8 seconds = 2 m + 4 m + 0 = 6 m

Thus, the net displacement of the object from t = 0s to t = 8s is 2 m.

The initial velocity of the object is 1 m/s.

The  final velocity of the object is 0 m/s.

The average velocity of the object from t = 0s to t = 8s is 0.25 m/s.

The distance traveled by the object in the first 8 seconds is 6 m.

A rectangular reflecting pool is 56.5 ft wide and 141 ft long. What is the area of the pool in square meters
konstantin123 [22]

By definition, the area of the pool is 740.112 m².

<h3>Definition of area</h3>

The area is the measure of a space delimited by a contour which is called perimeter.

That is, the area gives an idea of ​​how much surface a figure covers and is defined as the measure of the region or surface enclosed by a geometric figure.

<h3>Area of a rectangle</h3>

A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length.

The area of ​​a rectangle is calculated by multiplying the lengths of two contiguous sides of the figure which are different from each other, that is, the length is multiplied by the width:

Area= length× width

<h3>This case</h3>

A rectangular reflecting pool is 56.5 ft wide and 141 ft long. So, the area of the rectangular pool is calculated as:

Area= length× width

Area= 141 ft× 56.5 ft

Solving:

<u><em>Area= 7966.5 ft²= 740.112 m²</em></u> (being 1 ft²= 0.092903 m²)

So, the area of the pool is 740.112 m².
