What is the acceleration of your car if it has a force of 8000N acting upon
it, and it has a mass of 1000kg?

Answer:

6.86g/mL

Explanation:

The density of the metal would be approximately 6.859 grams per milliliter (g/mL).

Given that the mass (m) is 78.2 g and the volume (V) is 11.4 mL, we can plug these values into the formula:

Density is a physical property that quantitatively expresses how much mass is contained within a given volume of a substance. In other words, it is a measure of how tightly packed the particles or molecules of a material are. Mathematically, density is defined as the mass of an object (or substance) divided by its volume. It is often denoted by the Greek letter "ρ" (rho).

Density is defined as mass per unit volume. The formula for density is:

Density (ρ) = Mass (m) / Volume (V)

Density (ρ) = 78.2 g / 11.4 mL

Now, let's calculate the density:

Density (ρ) = 6.859 g/mL

So, the density of the metal is approximately 6.859 grams per milliliter (g/mL).

Explanation:

it gets filterd out

W = F × s

W = 15kN × 40 m

W = 15.000 N × 40 m

W = 600.000 J

P = W/t

P = 600.000 J/2 s

P = 300.000 Watt

P = 300kWatt

We have that with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

From the question we are told

Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?

Generally the equation for Momentum   is mathematically given as

P=mv

Therefore

[tex]m_1v_2=m_2v_2[/tex]

Hence

[tex]v_1=\frac{m_2v_2}{m_1}[/tex]

Therefore

[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]

Hence

[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]

Now

with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

Answer:

P = m (v2 - v1)     change in momentum

P = - m v1  if v2 is to be zero

F = P / t     change in momentum equals applied force

F = m a = - m v1 / t

a = -v1 / t     or a * t = -v1`

Any combination of a and t that is greater than v1 will bring the space station to a halt

If a is small then t must be large

Any applied force will eventually bring the ship to a halt and then begin the acceleration towards the starting point

Answer:

Final velocity = 7.4m/s

Explanation:

Use the equation:

acceleration = (final velocity - initial velocity)/time

Rearrange to get:

final velocity = (acceleration * time) + initial velocity

Now just substitute with the values you already have:

Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s

Final velocity = 7.36m/s

We are using 2 sig-figs, so:

Final Velocity = 7.4m/s
