The acceleration of one of those bugs is equal to 305mi/s.

<h3>Acceleration calculation</h3>

To calculate the insect's acceleration, the action and reaction force of the impact must be considered.

As the insect will hit the helmet, the force it hits is the same force it receives, so we can make the following expression:

                                          m_m \times a_m = m_b \times a_b

                                        550 \times 0.0027 = 5 \times 10^{-3} \times a_b

<em>Speed ​​has been converted to miles per second</em>

                                          a_b = 305 mi/s

So, the acceleration of one of those bugs is equal to 305mi/s.

Snezhnost [94]

Hi there!

Acceleration:

a = Δv / Δt, so:

a = 20/9 ≈ 2.22 m/s²

Displacement:

We can use the equation Δd = v₀t + 1/2at² to solve. (Initial velocity is 0).

Δd = 1/2at²

Plug in the acceleration and time:

Δd = 1/2(2.22)(9)² ≈ 89.91 m

A gold nucleus (with a radius of 6.5 fm in its rest system, containing 197 protons and neutrons of rest mass 939 MeV/c2 each) is
julia-pushkina [17]

Answer:

1.9982154567\times 10^{-18}\ kgm/s

762474.685899 MeV

3.1603639031 fm

Explanation:

v = 0.97 c

c = Speed of light = 3\times 10^8\ m/s

Relativistic momentum is given by

p=\dfrac{m_0v}{\sqrt{1-\dfrac{v^2}{c^2}}}\\\Rightarrow p=\dfrac{939\times 10^6\times 1.6\times 10^{-19}\times 0.97\times 3\times 10^8}{\sqrt{1-\dfrac{0.97^2c^2}{c^2}}}\\\Rightarrow p=\dfrac{(939\times 10^6\times 1.6\times 10^{-19})J/c^2\times 0.97c}{\sqrt{1-0.97^2}}\\\Rightarrow p=\dfrac{(939\times 10^6\times 1.6\times 10^{-19})\times 0.97}{c\sqrt{1-0.97^2}}\\\Rightarrow p=\dfrac{(939\times 10^6\times 1.6\times 10^{-19})\times 0.97}{3\times 10^8\times \sqrt{1-0.97^2}}\\\Rightarrow p=1.9982154567\times 10^{-18}\ kgm/s

The momentum is 1.9982154567\times 10^{-18}\ kgm/s

Energy in MeV

E=\dfrac{m_0c^2}{\sqrt{1-\dfrac{v^2}{c^2}}}\\\Rightarrow E=\dfrac{939}{\sqrt{1-0.97^2}}\\\Rightarrow E=3862.52987766\ MeV

Total energy is

E'=3862.52987766+7.9=3870.42987766\ MeV

The total energy is 3870.42987766 MeV

For all the nucleons

E_t=197\times 3870.42987766=762474.685899\ MeV

The energy is 762474.685899 MeV

Diameter = 2\times 6.5=13\ fm

From length contraction

D'=D\sqrt{1-\dfrac{v^2}{c^2}}\\\Rightarrow D'=13\sqrt{1-0.97^2}\\\Rightarrow D'=3.1603639031\ fm

The diameter would be 3.1603639031 fm
