Answer:
Explanation:
Given
Mass of mother 
Mother is released with a speed of 
Assuming we need to find elastic Potential energy stored in Trampoline
Kinetic energy acquired by Mother comes from Elastic Potential Energy stored in the spring
I.e. Elastic Potential Energy=Kinetic Energy of mother
So 246.875 J of Energy is stored in the trampoline as he pull the ring
The time taken by the stone to hit the ground would be 5.12 seconds.
<h3>What are the three equations of motion?</h3>
There are three equations of motion given by Newton
The first equation is given as follows
v = u + at
the second equation is given as follows
S = ut + 1/2×a×t²
the third equation is given as follows
v² - u² = 2×a×s
Keep in mind that these calculations only apply to uniform acceleration.
As given in the problem, a stone is dropped from the helicopter which is ascending at the speed of 19.6 m/s
height(S) = 156.8 meters
initial velocity(u) = -19.6 m/s
acceleration(a) = 9.81 m/s²
By using the second equation of motion given by newton
S = ut + 1/2at²
S = 156.8m ,u= -19.6 m/s , a= 9.81 m/s² and t =? seconds
156.8= -19.6t + 9.81t²
t = 5.12 seconds
Thus, the time taken by the stone to hit the ground would be 5.12 seconds.

<h2>Answers:</h2>
<h2>1. Differraction Pattern:
</h2><h2 />
The diffraction pattern is that formed when a wave is deflected when it passes through an opening or encounters an obstacle.
When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.
Note that the principal condition for the occurrence of this phenomena is that the obstacle must be comparable in size (similar size) to the size of the wavelength.
This means the smaller the slit or obstacle (diffracting object), the wider the resulting diffraction pattern, and the greater the obstacle, the narrower de resulting patter.
<h2>2. Diffraction Angle:
</h2><h2 />
Is the output resulting angle as measured from the surface that is normal (perpendicular) to the slit.
Now, if instead of a slit we have a diffraction grating, different wavelengths of light (different colors is we talk about the visible spectrum) will pass through the grating at different angles.
