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.

Hello!
We can compare these adjectives to things related to the ocean as seen below.
As fast as a sailfish.
As big as a whale
As cute as a clownfish
As quiet as a starfish
As smart as a dolphin
As cool as a dive in the ocean
As cold as the deep ocean
As cool as a coral reef
As quick as a swordfish
As strong as a shark
For the bonus you could say a seashell is beautiful. As beautiful as a seashell.
I hope this helps!

<u>The ozonosphere:</u></h3>
-is made of O3
-heats the air in the stratosphere
-absorbs ultraviolet rays from the sun
<u>note </u>: the ozonesphere is part of the stratosphere not the thermosphere.
: the mesophere is extremely cool/cold
Answer:
The problem tells you that
6 g
of hydrogen gas,
H
2
, react with an unknown mass of oxygen gas,
O
2
, to form
54 g
of water.
As you know, the law of mass conservation tells you that the in a chemical reaction the total mass of the reactants must be equal to the total mass of the products.
In your case, this can be written as
total mass of reactants
m
H
2
+
m
O
2
=
mass of product
m
H
2
O
This means that the reaction must have consumed
m
O
2
=
m
H

O
−
m
H
2
m
O

=
54 g
