A mass of 2.50 kg is in a gravitational field of 14.0 N/kg. What force acts on the mass?

Physics

Olenka [21]3 years ago

To determine the force that acts on the mass, just multiply the mass by the gravitational field. Using the given data,
                             F = (2.50 kg)(14 N/kg) = 35 N
Therefore, the force that acts on the mass is equal to 35 N.

Answer:

F= 2.5 Kg * 14 \frac{N}{Kg}= 35N

So then the force acting on the mass for this gravitational field is 35N

Explanation:

The gravitational field is defined as the force that acts on an object of mass m. By definition we have that :

F= ma from the second law of Newton.

In our case the value of a represent the acceleration or the gravitational field, so then the expression for the gravitational field is:

g = \frac{F}{m}

For this case we know that g= 14.0 \frac{N}{kg} and m=2.5 kg

So if we replace and find F we got:

F= 2.5 Kg * 14 \frac{N}{Kg}= 35N

So then the force acting on the mass for this gravitational field is 35N

A jet plane traveling 1890 km/h (525 m/s) pulls out of a dive by moving in an arc of radius 5.20 km. What is the plane's acceler
Tema [17]

Answer:

Acceleration of the plane, a = 5.4 g

Explanation:

It is given that,

Speed of the jet plane, v = 1890 km/h = 525 m/s

Radius of the arc, r = 5.20 km = 5200 m

The plane is moving in the circular path, the centripetal acceleration will act on it. It is given by :

a=\dfrac{v^2}{r}

a=\dfrac{(525\ m/s)^2}{5200\ m}

a=53.004\ m/s^2

We know that, the value of g is, g=9.8\ m/s^2

\dfrac{a}{g}=\dfrac{53.004\ m/s^2}{9.8\ m/s^2}=5.4

a=5.4\times g

So, the acceleration of the plane is 5.4 g. Hence, this is the required solution.

A plane is flying horizontally with speed
Kay [80]

Answer:

2. ahead of the package.

Explanation:

Using y' - y = ut - 1/2gt², we find the time, t it takes the package to hit the ground. So, u = initial vertical velocity of package = 0 m/s, y = initial position of package = 3970 m, y' = final position of package = 0 m, g = acceleration due to gravity = 9.8 m/s².

Substituting the variables into the equation, we have

y' - y = ut - 1/2gt²

0 m - 3970 m = 0t - 1/2 × (9.8 m/s²)t²

-3970 m = -(4.9m/s²)t²

t² = -3970 m ÷ -4.9 m/s²

t² = 810.2 s²

t = √810.2 s²

t = 28.5 s

Using v = u' + at, we find the horizontal acceleration of the plane. Since the initial horizontal velocity of the package is that of the plane, u' = 162 m/s, v = 0 m/s since the package stops and t = 28.5 s when the package stops.

So, a = (v - u')/t

a = (0 m/s - 162 m/s)/28.5 s

a = -162 m/s/28.5 s

a = -5.68 m/s²

Using v² = u'² + 2as, we find the horizontal distance ,s where the package stops.

So, s =  (v² - u'²)/2a

Substituting the values of the variables, we have

s =  ((0 m/s)² - (162 m/s)²)/(2 × -5.68 m/s²)

= - 162 m²/s²/(-11.36 m/s²)

= 14.26 m

The horizontal distance d the plane moves after releasing the package is d = u't = 162 m/s × 28.5 s = 4617 m

Since d = 4617 m > s = 14.26 m, the plane would be ahead of the package when the package hits the ground.

the earth orbits is oval in shape.explain how the mangnitude of gravitational between the earth and sun changes as the eart move
s2008m [1.1K]

As the distance between the Earth and the Sun decreases, the magnitude of gravitational force between the earth and sun increases and vice versa.

<h3>What is gravitational force?</h3>

Gravitational force is a force that attracts any two objects with mass.

According to Newton's law of universal gravitation, the force of attraction between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between the two objects.

F = Gm₁m₂/R²

where;

  • m₁ is mass of Earth
  • m₂ is mass of sun
  • R is the distance between the Earth and Sun

Thus, as the distance between the Earth and the Sun decreases, the magnitude of gravitational force between the earth and sun increases and vice versa.

What is the equation for time when using a position-time graph?
HACTEHA [7]

Answer:

This really depends on the graph but to approach these types of problems you can go about it this way (check explanation)...

Explanation:

(1) What is position?

Where is the object's location at?

If slope is zero, velocity is zero (straight line)

Slope positive, velocity is constant/ positive (linear line positive)

Object is accelerating.. curve upwards.

Steeper the slope, higher the speed

(2) What is velocity?
