Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².
<h3>What is the velocity formula?</h3>
It is given by the initial velocity plus acceleration multiplied by time, that is:
v(t) = v0 + at.
In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:
v(t) = v0 + at.
19.6 = 0 + 2a.
2a = 19.6.
a = 19.6/2.
a = 9.8 m/s².
The acceleration is of a = 9.8 m/s².

Answer:
x = 6 7/9
Step-by-step explanation:
Any triangle inscribed in a circle with one side being a diameter is a right triangle.
9x - 14 = 180 - 90 - 43
9x - 14° = 47°
9x = 61°
x = 6 7/9
