velocity=Vertical (y) info:

• y = -22.0 m

• viy = 0 m/s

• ay = -9.8 m/s2

velocity- motion

acceleration-increase in the rate or speed of something.

distance-Distance is a numerical measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria (e.g. "two counties over"). The distance from a point A to a point B is sometimes denoted as. .

time-a point of time as measured in hours and minutes past midnight or noon.

Explanation:

The soccer ball travels a horizontal distance of

33.9 m after being kicked with horizontal velocity of 18.8ms−1. Assuming air resistance is negligible.

Time of flight of the ball

t=Distance Speed=33.918.8s In the vertical direction kinematic equation is

height

h=ut+12gt2 Initial velocity uv=0, acceleration due to gravity g=9.81ms−2. Inserting various values we get h=0×33.918.8+12×9.81×(33.918.8)2⇒h=12×9.81×(33.918.8)2

⇒h=15.9m, rounded to 3 sig. figs

True I believe bc if you put a certain amount of force on an object it'll move and depending on where you place the force on the object it'll move in that direction. How much force and how much weight the object has will determine the speed...

Answer:

it's D

Explanation:

Newton's first law of motion states that a body at rest remains at rest or if in motion remains in motion at a constant velocity unless acted upon by a external Force

The correct option is D. In uniform motion will remain in motion unless it is acted upon by an outside force .

Unless influenced by an imbalanced force, an item at rest stays at rest, and an object in motion keeps moving in a straight path at a constant pace. An object's acceleration is determined by its mass and the force being applied.

Every time one object applies force to another, the other object applies an equal and opposite force to the first.

According to Newton's first law, unless pushed to alter its condition by the operation of an external force, every object will continue to be at rest or in uniform motion in a straight line. Inertia is the propensity to resist changes in a condition of motion.

Therefore, The correct option is D. In uniform motion will remain in motion unless it is acted upon by an outside force .

Answer:

9000Ns

Explanation:

Given parameters:

Mass of sled  = 100kg

Net force  = 150N

Time  = 1min  = 60s

Unknown:

Total impulse  = ?

Solution:

The total impulse on the body can be derived using the expression below;

   Impulse  = Force x time

  So;

      Impulse  = 150 x 60  = 9000Ns

Answer:

Please find the calculated values entered into the following table;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

Explanation:

The given parameters are;

The acceleration due to gravity, g ≈ 10 N/kg

The Gravitational Potential Energy, G.P.E. = m × g × h

The weight of the object, W = m × g

∴ G.P.E. = W × h

The table is filled using the above formula for calculations as follows;

For object A, we have;

Weight = 5 kg × 10 N/kg = 50 N

G.P.E. = 50 N × 2 m = 100 J

For object B, we have;

Weight = 2 kg × 10 N/kg = 20 N

G.P.E. = 20 N × 6 m = 120 J

For object C, we have;

Weight = 8 kg × 10 N/kg = 80N

G.P.E. = 80 N × 5 m = 400 J

For object D, we have;

Weight = 20 kg × 10 N/kg = 200 N

G.P.E. = 200 N × 0.6 m = 120 J

For object E, we have;

Weight = 5,000 kg × 10 N/kg = 50,000 N

G.P.E. = 50,000N × 2 m = 100,000 J

For object F, we have;

Weight = 0.2 kg × 10 N/kg = 2 N

G.P.E. = 2 N × 10 m = 20 J

For object G, we have;

Weight = 67 kg × 10 N/kg = 670 N

G.P.E. = 670 N × 44 m = 29,480 J

Therefore, we have the table filled as follows;

[tex]\left\begin{array}{ccccc}Object & Mass \ (kg)& Weight \ (N) & Height \ (m)&G.P.E.\\A&5&50&2&100\\B&2&20&6&120\\C&8&80&5&400\\D&20&200&0.6&120\\E&5,000&50,000&2&100,000\\F&0.2&2&10&20\\G&67&670&44&29,480\end{array}[/tex]

Answer:

D.   Most metals can be drawn into a wire, while nonmetals would break apart

Explanation:

The correct statement from the given choices is that most metals can be drawn into a wire while non-metals would break apart.

Metals are malleable due to the presence of metallic bonds between their atoms. The large electron cloud due to the electropositivity of metals allows for the wide range of physical properties observed in them.

Non-metals are brittle and cannot conduct neither heat nor electricity.

separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.

Answer:

Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate.

Answer:

The charge 3q must be placed at a distance of 1.73d away from the origin.

Explanation:

The electric field at the origin due to q at distance, d from the origin is E = q/4πε₀d².

The electric field at the origin due to 2q at distance, d from the origin is E' = -2q/4πε₀d². (It is negative since it its directed towards the negative x-axis)

Now, the net electric field at the origin due to both charges is thus E" = E + E' = q/4πε₀d² + (-2q/4πε₀d²) = q/4πε₀d² - 2q/4πε₀d² = -q/4πε₀d².

The electric field due to 3q at a distance x from the origin is E₁ = 3q/4πε₀x².

Now, the net electric field E' must cancel out E₁ so that the electric field at the origin is zero.

So, E' + E₁ = 0

E' = -E₁

-q/4πε₀d² = -3q/4πε₀x²

1/d² = 3/x²

taking inverse of both sides, we have

x²/3 = d²

multiplying both sides by 3, we have

x² = 3d²

taking square root of both sides, we have

x = (√3)d

x = ±1.73d

So, the charge 3q must be placed at a distance of 1.73d away from the origin.

Answer:

The air speeds up, and as it speeds up, its pressure—the force of the air pressing against the side of the object—goes down. ... This means that if the area in which the air is moving narrows or widens, then the air has to speed up or slow down to maintain a constant amount of air moving through the area.
