Answer: 5.5

Explanation: its simply different from the others

Answer:

19.1 m, 52.0°

Explanation:

Given:

v₀ₓ = 0 m/s

v₀ᵧ = 2.88 m/s

vᵧ = 0 m/s

aₓ = 0.350 m/s² cos(-52.0°) ≈ 0.215 m/s²

aᵧ = 0.350 m/s² sin(-52.0°) ≈ -0.276 m/s²

Find: Δx and Δy

First, find time.

vᵧ = aᵧt + v₀ᵧ

0 m/s = (-0.276 m/s²) t + 2.88 m/s

t = 10.4 s

Now find the displacement components Δx and Δy.

Δx = v₀ₓ t + ½ aₓ t²

Δx = (0 m/s) (10.4 s) + ½ (0.215 m/s²) (10.4 s)²

Δx = 11.7 m

Δy = v₀ᵧ t + ½ aᵧ t²

Δy = (2.88 m/s) (10.4 s) + ½ (-0.276 m/s²) (10.4 s)²

Δy = 15.0 m

The magnitude of the displacement is:

d² = Δx² + Δy²

d² = (11.7 m)² + (15.0 m)²

d = 19.1 m

The direction of the displacement is:

θ = atan(Δy / Δx)

θ = atan(15.0 m / 11.7 m)

θ = 52.0°

Answer:

ancient astronomy is back in the 1600s and is really old and modern astronomy is present and astronomy today

Time period and technology are the main differences between ancient and modern astronomy.

The main differences between ancient and modern astronomy is the era in which they were created and developed. The ancient astronomy developed by Greeks and technology for study is very old. The first documented records of systematic astronomical observations occurs in Assyro-Babylonians around 1000 BCE.

While on the other hand, modern astronomy refers to the astronomy that is developed in this modern period and use advance technology. Modern astronomy includes many elements of the motions as well as characteristics of moving bodies so we can conclude that time period and technology are the main differences between ancient and modern astronomy.

v₀ = 0 m/s

a = 3 m/s²

a. Find v

v² = v₀² + 2aΔx

v² = (0 m/s)² + 2 (3 m/s²) (2 m)

v = 3.46 m/s

b. Find t

Δx = v₀ t + ½ at²

Answer:

V= I x R =250 x 0.0198 = 4.95 Volts

Explanation:

The voltage across the resistor is 4.95 Volts.

Given that the resistance is 0.0198 ohms and the current flowing through the silver is 250 amps.

The voltage V across the resistor is the product of the current I flowing through the resistors and resistance R.

[tex]V = IR[/tex]

Substituting the values, we get the voltage.

[tex]V = 250 \times 0.0198[/tex]

[tex]V = 4.95 \;\rm V[/tex]

Hence we can conclude that the voltage across the resistor is 4.95 Volts.

Answer:

1609.3

Explanation:

Answer:

15.34 i think

Explanation:

Answer:

1) The ball will land approximately 141.4 m away from where it was kicked

2) The maximum height reached is approximately 61.22 m

3) The total hang time is approximately 7.07 seconds

Explanation:

First we list out the known parameters

The direction in which the punt is kicked, θ = 60°

The speed with which the punk is kicked, v₀ = 40 m/s

1) The distance away (the range, R) the ball will land is given by the equation;

[tex]R = \dfrac{v_0^2 \times sin(2\cdot \theta)}{g}[/tex]

Where;

g =  The acceleration due to gravity = 9.8 m/s²

Substituting the values, gives;

[tex]R = \dfrac{40^2 \times sin(2\times60^{\circ })}{9.8} \approx 141.4 \ m[/tex]

The distance away the ball will land ≈ 141.4 m

2) The maximum height is given m=by the following equation for vertical motion;

(v₀ × sin(θ))² = 2 × g × [tex]h_{max}[/tex]

Obtained from the equation of motion, v² = u² - 2×g×h where at maximum height;

v = 0 at maximum height, the ball stops upward motion

h = Height of motion = [tex]h_{max}[/tex] at maximum height

v, and u are the vertical component of the velocity, v₀

Substituting the values in the equation for the maximum height, gives;

(40 × sin(60))² = 2 × 9.8 × [tex]h_{max}[/tex]

(40 × (√3)/2)² = 1200 = 19.6 × [tex]h_{max}[/tex]

1200 = 19.6 × [tex]h_{max}[/tex]

[tex]h_{max}[/tex] = 1200/19.6 ≈ 61.22 m

The maximum height reached ≈ 61.22 m

3) The time to maximum height is given by the following equation of motion;

[tex]v_y[/tex] = v₀ × sin(θ) - g × t

[tex]v_y[/tex] = 0 at maximum height

We therefore have;

v₀ × sin(θ) = g × t

t =  v₀ × sin(θ)/g = 40 × sin(60°)/9.8 = (40 ×(√3)/2)/9.8 = 3.535 seconds

Given that the motion of the ball is symmetrical about the maximum height, we have;

The time from ground level to maximum height = The time from the maximum height back to the ground level

The total time hang time = The time from ground level to maximum height + The time from the maximum height back to the ground level

The total time hang time ≈ 3.535 + 3.535 ≈ 7.07 seconds.

The total time hang time ≈ 7.07 seconds.

Answer:

MA = 4

Explanation:

In order to solve this problem, we must use the definition of the ideal mechanical advantage, which tells us that it is equal to the relationship of the inclined distance over the height with respect to the level of the ground

MA = L / h

where:

MA = mechanical advantage

L = Length of the inclined plane = 10 [m]

h = elevation = 2.5 [m]

MA = 10/2.5

MA = 4
