Answer:146.8983 grams

Complete question is;

A ski jumper travels down a slope and leaves the ski track moving in the horizontal direction with a speed of 24 m/s. The landing incline below her falls off with a slope of θ = 59◦ . The acceleration of gravity is 9.8 m/s².

What is the magnitude of the relative angle φ with which the ski jumper hits the slope? Answer in units of ◦

Answer:

14.08°

Explanation:

The time covered will be given by the formula;

t = (2V_x•tan θ)/g

t = (2 × 24 × tan 59)/9.8

t = 8.152 s

Now, the slope of the flight path at the point of impact will be given by the formula;

tan α = V_y/V_x

We are given V_x = 24 m/s

V_y will be gotten from the formula;

v = gt

Thus;

V_y = gt

V_y = 9.8 × (8.152) = 78.89 m/s

Thus;

tan α = 78.89/24

tan α = 3.2871

α = tan^(-1) 3.2871

α = 73.08°

Thus ;

Relative angle φ = α - θ = 73.08 - 59 = 14.08°

Explanation:

Icicles melt from a rooftop

Answer:

47.4 ft/s

Explanation:

Using v² = u² - 2gs where u = initial vertical velocity of ball = 100sin30, v = final vertical velocity of ball at the time it was caught by the fielder, g = acceleration due to gravity = 32 ft/s² and s = vertical displacement = y₂ - y₁, y₁ = 3 ft and y₂ = 7 ft. s = y₂ - y₁ = 7 - 3 = 4 ft

Substituting these values into the equation, we have

v² = u² - 2gs

v² = (100sin30)² - 2 × 32ft/s² × 4 ft

v² = (100sin30 ft/s)² - 256 ft²/s²

v² = (50 ft/s)² - 256 ft²/s²

v² = 2500 ft²/s² - 256 ft²/s²

v² = 2244 ft²/s²

v = √2244 ft²/s²

v = 47.37 ft/s

v ≅ 47.4 ft/s

So, the velocity of the ball relative to the fielder at the instant the catch is made is 47.4 ft/s.

Answer:68

Explanation:

6.8x100

We have that for the Question "A block weighing (Fg) 100 N is resting on a steel table (us = 0.68) ." it can be said that

The minimum force to start this block moving is [tex]F_{min}=37N[/tex]

From the question we are told

A block weighing (Fg) 100 N is resting on a steel table (us = 0.68)

The minimum force to start this block moving is. N.

Generally the equation for the Maximum force  is mathematically given as

[tex]F_{max} =0.74*50\\\\F_{max} =37N[/tex]

Therefore

The Minimum force = max Frictional force

Therefore

[tex]F_{min}=37N[/tex]

Hence

The minimum force to start this block moving is [tex]F_{min}=37N[/tex]

Answer:

250 m

Explanation:

In projectile, range is given as;

R = (v²sin 2θ)/g

We are given θ = 45°

Thus range of shell is;

R = (v²sin (2 × 45))/g

R = v²/g

Now, distance for the shell to hit the car will be; 150 + 14.14t

This will be equal to the range of shell;

150 + 14.14t = v²/g

Where t is time of flight

Now, time of flight is given by;

t = (2vsin θ)/g

t = (2v sin 45)/g

In surf form, we have;

t = (2v/(g√2))

Simplifying further gives;

t = (v√2)/g

Plugging this value of t into the distance equation gives;

150 + 14.14(v√2)/g = v²/g

Assuming g is 10 m/s², we have;

150 + 14.14(v√2)/10 = v²/10

Multiply through by 10 to get;

1500 + 14.14(v√2) = v²

v² - 20v - 1500 = 0

From quadratic equation calculator, we have; v = 50 m/s

Thus, t = (50√2)/g

t = (50√2)/10

t = 5√2

Plugging this into the distance equation gives;

Distance = 150 + 14.14(5√2) = 250 m

An atom with a closed shell of valence electrons (corresponding to an electron configuration s2p6) tends to be chemically inert. An atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion.Explanation:

Explanation:

Answer: 6.0 m/s2

Explanation:

The acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².

In order to move a body of mass 'm' kg with an acceleration of 'a' m/s², a force of magnitude → |F| = ma is needed to push the body in a specified direction.

Given is a 2 kg block being moved across a frictionless horizontal surface by a 6 Newton horizontal force.

Mass of block [m] = 2 Kg

Force on block [F] = 6 N

From the definition of force -

|F| = ma

6 = 2 x a

6 = 2a

a = 3 m/s²

Therefore, the acceleration of the block pushed horizontally with the force of 6 N is 3 m/s².

Explanation:

i dont have a lot of context but this is what i thought of so...

Stars and planets form when dust and gas from space is pulled together by gravitation.

In mechanics, gravity, often known as gravitation, is the force of attraction that acts on all matter. It has little impact on determining the intrinsic characteristics of common stuff because it is by far the weakest known force in nature.

In contrast, it governs the formations and evolution of stars, galaxies, and the entire cosmos by its extensive and ubiquitous action, which affects the trajectories of objects in the solar system and beyond the universe. All objects on Earth experience weight, or a gravitational pull that is proportionate to their mass and is imposed by the planet's mass.

Hence, the stars and planets form when dust and gas from space is pulled together by gravitation.
