For this case we have the following equation:

Where, we have the following variables:
x: time in seconds
y: speed in feet per seconds
For the initial velocity, we evaluate x = 0 in the given equation:

Therefore, the initial speed is 12 feet per second.
Answer:
The particle's initially velocity is 12.
Answer:
The area of the clock 
Step-by-step explanation:
We have been given the face of the clock that is 
So that is also the circumference of the clock.
Since the clock is circular in shape.
So 
From here we will calculate the value of radius
of the clock that is circular in shape.
Then 
Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.
Now 
So the area of the face of the clock =
