The truck applies the same force to the car that the car applies to the truck. The truck applies the same force to the car that the car applies to the truck. According to Newton's third law, action and reaction have the same magnitude and move in the opposite direction.

Force is an external agent that can change the state of rest or motion of a body. It has a magnitude as well as a direction.

The direction of the force is the point where force is applied, and the application of force is the point where force is applied.

The concept of force is commonly explained in terms of Isaac Newton's three laws of motion, which are laid out in his Principia Mathematica.

The truck exerts the very same force on the car as the car exerts on the truck. The truck exerts this very same force on the car as the car exerts on the truck.

Action and reaction have the same amplitude and move in the opposite direction, according to Newton's third law.

Thus, this can be the comparison in the given scenario.

Your question seems incomplete, the complete question is:

Consider the collision between a car and a

light truck whose weights are equal (M = m). If they are moving at the same speed when they collide, compare the size (or magnitude) of the forces between the car and the truck. Friction is so small that it can be ignored.

Compare the forces if the light truck is standing

still when the car hits it.

Answer:

question 1 is centripetal acceleration question 2 is 4

Explanation:

centripetal acceleration basically is acceleration that only changes velocity but not speed, while for question 2, you divide 10 by 2.5

Answer:

i dont understand sorry

Answer:

-2.68m/s²

Explanation:

To find acceleration use the formula:

acceleration = change in velocity ÷ time

Substitute in the values:

acceleration = -8.3 ÷ 3.1

acceleration = -2.67741.. ≈ -2.68m/s²

Answer:

The magnitude of the adhesive force allows the top block to remain

attached to the bottom when the blocks and the wire are balanced.

The option that must be true is; [tex]\mathbf{W_{bottom} = F_{adhesion}}[/tex]

Reason:

The tension exerted by the wire attached to the top block = T

Magnitude of the adhesive = [tex]F_{adhesion}[/tex]

Weight of the top block = [tex]W_{top}[/tex]

Weight of the bottom block = [tex]W_{bottom}[/tex]

Given that with the exertion of the tension, the two blocks remain at rest, we have;

The adhesive causes the bottom block to remain attached to the top block, we have;

Therefore, the magnitude of the adhesive force adds the bottom weight, to the top, weight, which gives;

The magnitude of the adhesive force = The weight of the bottom block

Therefore;

Answer:

v2^2 - v1^2 = 2 g s        fundamental formula

v2 = v1 + 2 g    = v1 + 19.8         increase in velocity in 2 sec

v1^2 + 39.6 v1 + 392 - v1^2 = 2 * 9.8 * 123.1 = 2412.76

v1 = (2412.76 - 392) / 39.6 = 51.03

v2 = 51.03 + 19.6 = 70.63

T = 70.63 / .8 = 7.207 sec     time to fall height of tower

S = 1/2 g T^2 = 4.9 * 7.207^2 = 254.5 m

(Note  v2^2 - v1^2 = 70.63^2 - 51.03^2 = 2385 m

2385 / (2 * 9.8) = 122 m (close to 123.1    as was given

Answer:

For example, one method for estimating the length of time it takes something to occur is to time it once using a stopwatch. You can reduce the uncertainty in this estimate by repeating the measurement and taking the average.

There are a lot of way to reduce the uncertainty however with real life sciences like quantum mechanics it will reveal more about the world and life if we have better measuring tools. Being precise is essential to understanding many parts of life.

Explanation:

The unknown variables in the model equation for ball's motion include vertical distance traveled by the ball which is 31.86 m and the final velocity of the ball which is 25 m/s.

The given parameter;

The equations that model the motion of the ball is given as follows;

[tex]h = v_0_y + \frac{1}{2} gt^2[/tex]

[tex]v_f = v_0_y + gt[/tex]

The force is different because of the amount of weight applied so the answer is A

The force that makes a difference in the weight of each person is Gravitational. Correct option is B.

Gravitational force is a fundamental force of nature that exists between any two objects with mass. It's the force that keeps us and everything else on Earth anchored to its surface. This force is proportional to the mass of the objects involved and inversely proportional to the square of the distance between them.

For example, if you were standing on a bathroom scale, the reading on the scale represents the force of the Earth's gravity acting on your body, which is why it's often referred to as your "weight." The actual mass of an object remains constant regardless of its location, but its weight can vary depending on the strength of the gravitational field at different locations (e.g., the weight on the Moon would be less than on Earth due to the Moon's weaker gravitational pull).

Answer:

resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Explanation:

assume that the ship started moving from A to B (north at 50km/hr for 2 hours) so the covered distance will be: 50*2 = 100 km

then it moves from B to C so the covered distance will be: 3*60 = 180 km

using Pythagoras, we get the resultant displacement = 20√1o6 km = 205912.6 m in the direction of western north.

Answer:

Solubility in gasses and liquids increase as pressure increases. This is due to colligative properties. The nitrogen gas levels would increase the farther the diver dives due to the increase of pressure causing the solubility of the nitrogen to increase, thus increasing the amount of it as you go deeper in the ocean.

Explanation:

As they plummet down, the driver would be in more risk. The solubility of gases and liquids increases as pressure increases. This is due to the existence of colligative properties. The nitrogen gas levels grow when the diver descends further into the water due to increased pressure, which causes the nitrogen's solubility to rise, increasing the amount of nitrogen present.
