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.

Answer: 10
Explanation:
When the number removed, the mean change from 12 to 11, so we assume that the removed number, x, has related to the median.
To find the removed number x, we sat their average equal to 11.
(12 + x) /2 = 11
12 + x = 22
x = 10

Explanation:
The length of the segment GH is 43.57 cm.
<h3>What is segment?</h3>
A segment is a part of a line or circle or arc or any geometric figure.
In Δ FGH, side GH is opposite to ∠F
Using the trigonometric ratio of sine,
Sin (angle) = Perpendicular /Hypotenuse
Given the ∠F = 33 and the sides FH = 80cm , GH = x
sin(F) = GH/FH
sin(33) = x/80
0.5446390= x/80
x = 43.57 cm
Thus, the length of segment GH = 43.57 cm
