Answer:

The friction of the moving object is proportional and perpendicular to the normal force

The friction of the moving object is proportional and perpendicular to the normal force. The friction experienced by the object is dependent on the nature of the surface it is in contact with. Friction is independent of the area of contact as long as there is an area of contact.

Answer:

954.4m/s

Explanation:

For a free falling object,it has constant acceleration and a changing velocity.

By using the velocity-time formula, the velocity can be obtained.

The height the rock travelled is the distance.

From,

Velocity (v) = Distance (d) / Time(t)

v = 3245m/3.4s

v = 954.4m/s

Energy is defined as the measurement of ability to do work.

Here,

Energy is the measurement of ability do work, which is a physical property of matter. Energy is of various types such as kinetic energy, potential energy,  thermal energy, electrical energy, heat energy, etc. Energy and its applications are associated with many laws. The study of energy and the laws associated with them is one of the main branch of physics.

Matter is defined as the substance that has a specific mass and occupies physical space. Atomic particles such as electrons, protons and others are material particles. Thus the study of these matter and material particles is an important branch of physics.

Matter and energy in nature interacts in many ways. Material particles moving moving with particular kinetic energy is an example of matter-energy interactions. These interactions and their studies comes under physics.

Object at rest :

*An object is said to be at rest if it does not change its position with respect to its surroundings with time.

Object at motion:

*An object is said to be in motion if the position changes with respect to it surrounding and time.

Answer:

Objects at rest: Objects at rest are ones that have no motion in them and will be stable in the same position. They have potential energy.

Objects at motion: Objects at motion are ones that are constantly in motion and a consistent velocity until they are acted upon by an unbalanced force. They have kinetic energy.

Answer:

Mass and volume

Explanation:

Density is determined by two types of measurements mass and volume. The resulting density value is typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L).

Density is determined by two types of measurements:

Mass: Mass is the amount of matter present in an object. It is typically measured in units such as grams (g) or kilograms (kg).

Volume: Volume is the amount of space occupied by an object. It can be measured in units such as cubic centimeters (cm³) or liters (L).

To calculate density, you divide the mass of an object by its volume. The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

The resulting density value is typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per liter (kg/L).

Answer:

Her displacement is 0 miles and her distance is 5 miles.

Explanation:

Given information:

Sophie runs in an oval track. The length of track is 5 m.

Distance is the total length of path covered during motion while displacement is the shortest distance between initial and final position.

In this case, Sophie completes one cycle in the oval track and the track length is 5 m. So, the distance covered by her will be 5 m.

Now, after completing the track, the initial and final position of Sophie will be same and hence, the displacement she covered will be 0 miles.

Therefore, option "Her displacement is 0 mile and her distance is 5 miles" is correct.

For more details, refer the link:

The displacement of Sophie is 0 and her distance is 5 m

The displacement of Sophie is the change in her position.

If she runs in an oval track, she will return to her initial starting position. The initial position and the final position will be equal, the change in her displacement will be zero.

[tex]\Delta x = x_f- x_i\\\\\Delta x = 5 - 5 = 0[/tex]

The distance traveled by Sophie is the sum of the total distance covered.

distance = 5 m

Thus, the displacement of Sophie is 0 and her distance is 5 m

We know that in cinematic problems the velocity in different directions is independent, so on the y-axis, or the y-velocity we have the gravity acceleration changing the velocity, although on the x-axis, or the x-velocity we don't have any acceleration, so the velocity is constant, so, we can use the basic cinematic equations and adapt them for our problem:

                                     [tex]\Large\displaystyle\text{$\begin{gathered}S_x = S_{x_0} + v_x t\\ \\v_y = v_{y_0} - gt \\ \\S_y = S_{y_0} + v_{y_0}t - \frac{gt^2}{2}\end{gathered}$}[/tex]

We can simplify it, we know that all the initial position on the x-axis is zero, but the initial position on the y-axis is 30, we also know that the initial velocity on y-axis is zero, so

                                           [tex]\Large\displaystyle\text{$\begin{gathered}S_x = v_x t\\ \\v_y =- gt \\ \\S_y = S_{y_0} - \frac{gt^2}{2}\end{gathered}$}[/tex]

I won't put numbers know, let's do all the manipulation first.

When the ball hit the ground we know that his position is 0 on the y-axis, so

                                           [tex]\Large\displaystyle\text{$\begin{gathered}0 = S_{y_0} - \frac{gt^2}{2}\\ \\S_{y_0} = \frac{gt^2}{2}\\ \\t = \sqrt{\frac{2S_{y_0}}{g}}\end{gathered}$}[/tex]

Now we know when the ball hits the ground, so we can use this time on the position equation on the x-axis and find out the distance the ball travelled
