In the sentence given, the "personal a" is:
Not necessary
So the complete sentence is:
¿Entiendes las palabras de tu profesora?
<h3>What is the "personal a"?</h3>
This is Spanish grammar exercise. The "personal a" is an "a" that precedes a specific person or a person that is used as a direct object.
In the sentence given, the "a" is not used because the direct object is "las palabras" which means "the words" and it is not a person.
For example:
- Adoro a mi mamá.
- Le llegó una carta a mi vecina.

58 percent because you divide 29 by fifty and you get the first 2 digits after the decimal.
Answer:

Explanation:
because excperencing that they become used to it and though they know it is bad, they are still very much used to it.
The acceleration of the pendulum mass D is; r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
<h3>What is Kinematics of particles?</h3>
Kinematics is the study of the geometry of motion of particles, rigid bodies, etc., disregarding the forces associated with these motions. However, Kinematics of a particle is the motion of a point in space.
From the sample problem, we can solve it using the (x, y, z) coordinate system to get;
r_c = x(t) i
r_d = [x(t) + l sin θ]i + l cos θ j
Finding the first derivative of r_d gives velocity as;
r'_d = [x'(t) + lθ' cos θ]i - lθ' sin θ j
Taking the second derivative of r_d gives the acceleration as;
r"_d = [x''(t) + lθ'' cos θ - lθ'² sin θ]i - l[θ'' sin θ - θ'² cos θ]j
A sample problem of kinematics of particles is;
A block C slides along the horizontal rod, while a pendulum attached to the block can swing in the vertical plane. Find the acceleration of
the pendulum mass D.
