Sarah wants to find out how much time it would take to drive from her home to New York. At an average, she would drive at 55 miles per hour. If the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)? O 13 hours 21 hours 29 hours 34 hours
I don't know if i understand but i believe your answer is (D)V
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.

The two statements that refer to the certificate of deposits are:
- It can be purchased from a banking institution.
- It can be purchased for almost any amount.
<h3>What is a certificate of deposit?</h3>
This is also referred to as time deposit. The deposit is a certificate that is issued to a person that is keeping money in a bank for a particular time period at a given rate of interest.
This certificate is gotten for almost any amount of money from the banks that are issuing them.

The justification of the third step in her proof of the property of logarithms is;
; Power rule of exponents
<h3>What are properties of Logarithms?</h3>
From the full question, the second step stopped at;

Now, according to Power Rule for Exponents we know that (a^m)ⁿ = a^(m*n). That means that to raise a number with an exponent to a power, we will multiply the exponent times the power.
Thus,
will give us
