For this case we have an equation of the form:
h (t) = (1/2) * a * t ^ 2 + vo * t + h0
Where,
a: acceleration
vo: initial speed
h0: initial height
t: time
We have then that the equations:
h (t) = - 16t ^ 2 + 19t + 110
Therefore, the initial velocity is given by:
vo = 19 feet / s
Answer:
The initial velocity when the rock is thrown is:
vo = 19 feet / s
The measure of the interior angle at vertex C is D. 144.
<h3>How to calculate the angle?</h3>
Based on the information given, the angle will be calculated thus:
8x + 8x + 8x + 3x + 3x = (5 - 2) × 180
30x = 540
Divide both side by 30
30x/30 = 540/30
x = 18
Therefore, at vertex C, we have 8x. This will be:
= 8x
= 8 × 18
= 144
