Angular velocity means how many radians/degrees is this hand passing by every second.
First, you realize it goes through a whole revolution (2

in radians) in 60 seconds.
This means for every second, it passes by:

For the next part, you need to know this equation:
Tangential velocity=Angular velocity x radius (meters)

Answer: it’s D

The best answer would be a "non-directional hypothesis"
Answer:
a. 
b. 
c. 
Explanation:
Given,
*initial velocity of the ball = 
*angle of projection = \theta_i
Horizontal component of the initial velocity of the ball = 
vertical initial component of the initial velocity of the ball = 
part a
From the kinematics,
In the y-direction motion,
total vertical displacement of the ball during the whole motion is zero.
Ball is moving under the gravitational acceleration, therefore the acceleration of the ball = -g, because gravitational acceleration always acts in the downward direction,
Let t be the time of flight of the whole motion,

part b.
At the peak of the path of the ball, the vertical component of the velocity of the ball becomes zero, only horizontal component of the velocity acts on the ball is equal to = 
part c.
Initial vertical component of the velocity of the ball =
