Answer:
a) 
b) 
Explanation:
From the exercise we got our <u>initial data</u>

a) To find <u><em>maximum height</em></u> we know that at that point 


Solving for y

b) Since we know that the ball strikes the fairway 190 m away

Solving for t

Now, we can calculate the speed of the ball in both axes



The <em>negative</em> sign means the direction of the ball at that point.
The contrast between total internal reflection and refraction is that total internal reflection is the full underwater build with no defeat of brightness, whereas refraction is the shift in the path of a tide that is parting from one medium to another.
