Answer:
h = 9.57 seconds
Explanation:
It is given that,
Initial speed of Kalea, u = 13.7 m/s
At maximum height, v = 0
Let t is the time taken by the ball to reach its maximum point. It cane be calculated as :
t = 1.39 s
Let h is the height reached by the ball above its release point. It can be calculated using second equation of motion as :
Here, a = -g
h = 9.57 meters
So, the height attained by the ball above its release point is 9.57 meters. Hence, this is the required solution.

The first term in the binomial is "x2", the second term in "3", and the power n is 6, so, counting ... x12 + 18x10 + 135x8 + 540x6 + 1215x4 + 1458x2 + 729 ... So memorize the Theorem and get the easy points.
A ) <em>Speed</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>scalar quantity and velocity is a vector quantity.</em>
When blue and orange color are given, then : Blue color has shorter wavelength and more energy as compared to orange.
<h3>What is visible spectrum?</h3>
Visible spectrum is that portion of electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light and human eye responds to wavelengths from about 380 to about 750 nanometers
Visible light comes in all the colors of the rainbow where each color has its own special frequency and wavelength. When all the colors are together, they make "white" light that we see.
Blue light has shorter wavelength more energy whereas orange light has the longer wavelength and low energy.

Answer:
<h2>Acceleration: </h2>
The rate of change of velocity is acceleration. Like velocity, acceleration is a vector and has both magnitude and direction. For example, a car in straight-line motion is said to have forward (positive) acceleration if it is speeding up and rearward (negative) acceleration if it is slowing down.
