For any given motion, the distance is
Explanation:
Explanation:
Given:
v₀ = 5.0 m/s
a = 2.5 m/s²
Equation:
Δx = v₀ t + ½ at²
Δx = (5.0 m/s) t + ½ (2.5 m/s²) t²
Δx = 5t + 1.25t²
Make a table of data using 1.0 increments for t.

What is happening to the heat in freezing?
Answers
Answer:
Heat is released.
Explanation:
Freezing is almost always an exothermic process, meaning that as liquid changes into solid, heat and pressure are released. This is often seen as counter-intuitive, since the temperature of the material does not rise during freezing, except if the liquid were supercooled.

What inertia is present in a stretched rubber?
Answers
Answer:
You input potential energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this is kind of potential energy is specifically called elastic potential energy.
The inertia in the stretched rubber will be potential energy, i.e., elastic potential energy.
What is inertia?Law of inertia:
Newton's First Law of Motion (Inertia) is an object at rest remains at rest, an object in motion remains in motion at constant speed through straight line unless acted by an unbalanced force.
Moment of inertia:
The sum of the product of mass of each particle with the square of its distance from the axis of the rotation is known as inertia or the moment of inertia.
Formula of Moment of Inertia I = Σ miri².
The three types of inertia are as follows:
Inertia of Rest.Inertia of motion.Inertia of Direction.Inertia is the result of conservation of energy.

Use Hooke's Law and Newton's 2nd Law to derive a formula for the acceleration of an object of mass m on a frictionless surface which is attached to a spring with a constant k which is stretched a distance L. The acceleration should be in terms of m, k, and L.
Answers
Answer:
a = kL/m
Explanation:
Here we can use Hooke's Law to find out the force applied on the system. Hooke's Law states that when a spring is stretched by some force, the force applied is directly proportional to the displacement of spring. The formula is given as:
F = kL
Now, the Newton's Second Law of motion states that whenever an unbalanced force is applied to a body it produces an acceleration in the body, in its own direction. So, the force is given by the formula:
F = ma
Comparing both the forces, we get:
kL = ma
a = kL/m

How many joules of potential energy does the pendulum have when it has 100 J of kinetic energy?
Answers
Answer: The maximum kinetic energy is 100 j.
Explanation: The kinetic energy = (potential energy) + (kinetic energy) and the potential energy of 0 J implying its kinetic energy is 100 J, which is its maximum.
If the maximum kinetic energy of the pendulum is 100 J, then the maximum potential energy of the pendulum will be 100 J as well.
The given parameters;
Kinetic energy of the pendulum = 100 JBased on the principles of conservation of mechanical energy, energy is always conserved.
If the maximum kinetic energy of the pendulum is 100 J, then its maximum potential energy will be 100 J as well.
M.A = K.E + P.E
where;
K.E is the kinetic energy P.E is the potential energyAt the lowest displacement of the pendulum;
M.A = K.E + 0
M.A = K.E = 100 J
At maximum displacement of the pendulum;
M.A = 0 + P.E
M.A = P.E = 100 J
Thus, if the maximum kinetic energy of the pendulum is 100 J, then the maximum potential energy of the pendulum will be 100 J as well.

What is the magnitude of the total displacement of the school bus from the start to the end of its trip?
Answers
Answer:
With the given information, we can assume that the start and the end of the trip are the same place. (Suppose, a tour where the bus starts at the school, then it goes to a given location, and then it returns to the school)
Now, the definition of displacement is:
The difference between the final position and the initial position.
But if the start and the end of the trip are the same place, then the initial and final position must be the same. Then the difference between the final position and the initial position is zero.
This means that the displacement of the school bus from the start to the end of its trip must be zero.
A wave traveling at 50.0 m/s has a wavelength of 10.0 m. What is the frequency of the wave? Show your work below?
Answers
Answer:
The frequency of the wave is 5 Hz
Explanation:
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. It is expressed in units of length (m).
Frequency is the number of vibrations that occur in a unit of time. Its unit is s – 1 or hertz (Hz).
The propagation velocity is the speed with which the wave propagates in the medium, that is, it is the magnitude that measures the speed at which the wave disturbance propagates along its displacement. Relate the wavelength (λ) and the frequency (f) inversely proportional using the following equation: v = f * λ.
In this case:
v= 50 [tex]\frac{m}{s}[/tex]f=?λ= 10 mReplacing:
50 [tex]\frac{m}{s}[/tex] = f* 10 m
Solving:
[tex]f=\frac{50 \frac{m}{s} }{10 m}[/tex]
f=5 Hz
The frequency of the wave is 5 Hz
