Answer:
50°
Explanation:
The law of reflection states that when a ray of light falls of a plane mirror or a smooth conducting surface, the angle of incidence is equal to the angle of reflection.
This law can be illustrated using the attached diagram where i = r
Now, for the given:
angle of reflection = angle of incidence = 50°
Hope this helps :)

Answer:
v = 16.49 m/s
Explanation:
Given that,
Length of the string, l = 1.15 m
The ball makes 137 complete turns each minute.
We know that, 1 turn = 6.28 rad
137 turns = 860.79 rad
1 min = 60 s
We need to find the tangential velocity of the ball. It can be given by
So, the tangential velocity of the ball is 16.49 m/s.
