Explanation:

Since the acceleration is constant, we use the big four equations.

[tex]x = x _{i} + vt[/tex]

[tex]x = \frac{1}{2} a {t}^{2} + v _{i}t + x _{i}[/tex]

[tex]v {}^{2} = (v _{i}) {}^{2} + 2a(x - x _{i})[/tex]

[tex] \frac{1}{2} (v + v _{i})t = x - x _{i}[/tex]

Next. identity the variables.

We know

t=9.2

change in position or (x- x_i) is 428.8

Initial Velocity is 0.

We need to solve for the final velocity, so we use the fourth equation.

[tex] \frac{1}{2} (v - v _{i})t = x - x _{i}[/tex]

Subsitue

[tex] \frac{1}{2} (v - 0)(9.2) = 428.8[/tex]

[tex] \frac{1}{2} (v)9.2 = 428.8[/tex]

[tex]v = 93.22 \frac{m}{s} [/tex]

For an airplane whose speed is 60 m/s is flying at an altitude of 500 m over the ocean toward a stationary sinking ship, the horizontal distance  is mathematically given as

x=606m

Generally, the equation for the y axis distance  is mathematically given as

y=vt+0.5gt^2

Therefore

500=0t+1.2(9.8)t^2

(a) The turtle's initial velocity is 4 m/s, initial position of the turtle is 5 cm, and initial acceleration is -1.25 m/s².

(b) The time when the velocity of the turtle is zero is 3.2 s.

(c) The time taken for the turtle to return to its starting point is 6.4 s.

(d) The time taken for the turtle to travel 30 cm is 0.08 s.

The initial velocity of the turtle is calculated as follows;

[tex]v = \frac{dx}{dt} \\\\x = 5 + 4t -0.625t^2\\\\v(t) = 4 - 1.25t\\\\v(0) = 4-0\\\\v(0) = 4 \ m/s[/tex]

The initial acceleration of the turtle is calculated as follows;

[tex]a = \frac{dv}{dt} \\\\v(t) = 4 - 1.25t\\\\a = -1.25\ m/s^2[/tex]

x(t) = 5 + 4t - 0.625t²

x(0) = 5 cm

v(t) = 4 - 1.25t

0 = 4 - 1.25t

1.25t = 4

t = 4/1.25

t = 3.2 s

The total distance traveled is calculated as follows

v² = u² + 2ad

0 = (4)² + 2(-1.25)d

0 = 16 - 2.5d

2.5d = 16

d = 16/2.5

d = 6.4 m

Time to travel the given distance;

d = ut + ¹/₂at²

6.4 = (4)t + ¹/₂(-1.25)t²

6.4 = 4t - 0.625t²

0.625t² - 4t + 6.4 = 0

solve the quadratic equation using formula method;

t = 3.2 s

The time travel the distance two times, = 2 x 3.2 s = 6.4 s

d = ut + ¹/₂at²

0.3 = (4)t + ¹/₂(-1.25)t²

0.3 = 4t - 0.625t²

0.625t² - 4t + 0.3 = 0

solve the quadratic equation using formula method;

t = 0.08 s

Explanation:

meteor impact this ecological processes is most likely responsible for the formation of the crater. Hence option D is correct.

A collision between celestial objects that has quantifiable effects is called an impact event. The most frequent impact events involve asteroids, comets, or meteoroids and have little impact. However, impact events have been shown to occur often in planetary systems and have physical repercussions. However, many surface impacts are reduced by atmospheres through atmospheric entry when massive objects strike terrestrial planets like the Earth. Nonetheless, there may be major physical and biospheric effects. The majority of the solid objects in the Solar System are covered with impact craters and structures, which provide the best empirical evidence for their frequency and size. Since the birth of the Solar System, impact events appear to have had a substantial impact on how the Solar System has changed. Significant impact events have impacted Earth's history and have been linked

Explanation:

Answer:

Explanation:

The kinetic friction between crate and the surface can be calculated as follows: [tex]f_{k}=\mu_{k}N=\mu_{k}mg=(0.24)(2)(10)=4.8 N[/tex]

Assume that the direction of the 10 N constant force is on the right, the kinetic friction will go the left, then:

[tex]\sum F=F_{net}=F-f_{k}=10-4.8=5.2 N[/tex]

A constant force of 10 N is applied to a crate of mass 2 kg on a rough surface, then the net force on the crate is 5.2 N

Friction is the resistance to a thing sliding or rolling over another solid object. Although frictional forces can be helpful, such as the traction required to walk without sliding, they also provide a significant level of resistance to motion.

The forces of attraction, also called as adhesion, between both the contact zones of the surfaces, that are always microscopically uneven, seem to be the main contributor to friction among metals.

These "welded" joints are sheared, and friction is created by the irregularities of a harder surface scuffing down against the softer surface.

From the given data in the question,

Firstly, calculate the friction between the crate and the surface,

[tex]f_k\\[/tex] = [tex]\mu_k[/tex]mg

= (0.24)(2)(10)

= 4.8 N

Now, let's calculate the net force,

ΣF = F(N) = F - [tex]f_k[/tex]

= 10 - 7.8

= 5.2 N

Therefore, the net force will be equal to 5.2 N.

The period (T) of the right pendulum for small displacements in s is equal to 1.49 seconds.

Mathematically, the time taken by this pendulum to undergo a small displacement is given by this formula:

[tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

Where:

Scientific data:

Acceleration due to gravity (g) = 9.8 m/s².

Assuming a randomized variable for the length of the rope to be 1.2 meter. Also, we know that the right pendulum has a radius of 1/2L.

1/2L = L/2

L/2 = 1.1/2

L/2 = 0.55 meter.

Substituting the parameters into the formula, we have;

[tex]T=2\times 3.142 \sqrt{\frac{0.55}{9.8} }\\\\T=6.284 \times \sqrt{0.0561} \\\\T=6.284 \times 0.2369[/tex]
