Did DART apply a balanced or unbalanced force to the satellite during the collision? What evidence supports your answer?

Answers

Answer 1

Answer:

A collision is an interaction between two objects that have made contact (usually) with each other. As in any interaction, a collision results in a force being applied to the two colliding objects. Newton's laws of motion govern such collisions

Answer 2

An interaction between two items that have made contact with one another  is referred to as a collision. A collision exerts a force on the objects interacting, just like any other interaction. Such collisions are regulated by Newton's laws of motion.

What is collision?

In physics, a collision, which is also known as an impact, is the abrupt, violent coming together and in near vicinity of two bodies, such as two pool cues, a golf club and a ball, a hammer as well as a nail, two railroad cars when linked, or a falling item and a floor.

The force and the amount of time the objects are in touch, in addition to the materials the two objects are made of, have an impact on the outcome of the impact. Generally,is common knowledge that a hardened steel ball bounced on a steel plate would rebound almost to the original position from where it was dropped, while a ball made of putty and lead will not.

a school bus slows to a stop with an average acceleration of -2m/s. the bus had an initial speed of 10m/s how long will it take the bus to come to a stop

Answers

It will take 2.5 seconds for the school bus to come to stop.

The initial velocity U of the School bus is 10m/s. As the bus has to come to stop, the final velocity V of the school bus will be 0 m/s.

The Acceleration a is -2m/s² and constant.

Because the Acceleration is constant. We can use the equations of motion,

Let say the School bus stopes after Reaching a distance D.

So, applying the equation of motion,

Since, ABCDEF is a regular hexagon,

The measure of the central angle of a regular polygon = [tex]\frac{360}{n}[/tex]

where n = number of sides of the polygon

The measure of the central angle of a regular hexagon =[tex]\frac{360}{6}[/tex] = 60°

That means when we rotate a regular hexagon by an angle in the multiple of 60°, the hexagon overlaps itself.

Therefore, by the rotation of 240° clockwise, point C will replace the position of point A.

The image of hexagon ABCDEF will become CDEFAB.

A rotation matrix is a transformation matrix in linear algebra that is used to make a rotation in Euclidean space. Rotation matrices depict rotations about the origin since matrix multiplication has no effect on the zero vector (the coordinates of the origin). Rotation matrices provide an algebraic description of such rotations and are widely utilized in geometry, physics, and computer graphics computations. In some publications, the term rotation is broadened to cover improper rotations, which are defined by orthogonal matrices with determinants of 1 (rather than +1).

To derive components are displacement(s), velocity, time(t), and acceleration(a). :

The 1st equation of motion is : v = u + at

The 2nd equation of motion is : S = ut + (1/2)at²

Given, the initial velocity of an object u = v₀ in an upward direction so it will be negative, u = - v₀

The displacement of an object is the height of the object from the ground S = H and It is downward so it will be positive.

The acceleration = g as the object moving towards the ground ( positive in downwards ). The final velocity of the object is V before it hits the ground.

Using the 3rd equation of motion to find the velocity of the object,

Answers

The oil filter for our car to be tightened with a torque of 30 n⋅m. we are using a 15-cm-long oil filter wrench, and we apply a force at the very end of the wrench in the direction that produces maximum torque is 200N.

What is a force?

A force is an effect that can alter an object's motion according to the physics. A force can cause object with mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe the force is as a push or a pull. A force is a vector quantity since it has both the magnitude and direction. It is calculated using newton SI unit (N). Force is denoted by the letter F. (formerly P).

The net force acting on an object is equal to rate at which its momentum varies over time, according to Newton's second law in its original formulation. This law suggests that object's acceleration is directly proportional to the net force acting on it, is in the direction of the net force, and is inversely proportional to the mass of the object if the object's mass is constant.

Thrust, which increases an object's velocity; drag, which decreases an object's velocity; and torque, which causes the changes in an object's rotational speed, are all concepts connected to force. Each part of an extended body often exerts the stresses on the sections that are nearby; the distribution of these forces throughout the body is what is known as the internal mechanical stress. Due to the balance of forces, such internal mechanical stresses do not generate acceleration of that body. Pressure is a straightforward form of the stress that, if unbalanced, can cause the body to accelerate. Pressure is distribution of several small forces applied over an area of a body. Stress typically results in flow of fluids or the deformation of solid materials.

Answers

The boat's speed relative to the ground when it is heading east with the current is 18.7 m/s and west against the current is -14.1 m/s.

In the first case,

The velocity of the boat concerning water= 16.4 m/s

The velocity of the water concerning ground= 2.3 m/s

By using the formula of relative velocity:

V(b, g)= V(b, w) + V(w, g)

V(b, g)= 16.4i + 2.3i m/s

V(b, g)= 18.7i m/s

Hence, the magnitude of the velocity of the boat concerning the ground is 18.7 m/s along the current.

In the second case,

The velocity of the boat concerning water is -16.4 m/s

The velocity of the water concerning the ground is 2.3 m/s

By using the formula for relative velocity:

V(b, g)= V(b, w) + V(w, g)

V(b, g)= -16.4i + 2.3i

V(b, g)= -14.1i m/s

S = 1/2 at^2

a= 2S/ t^2

a = 2(110m)/ (5.21 s)^2

a = 8.10 m/s^2

a metal sphere is half-filled with ammonia as part of a refrigeration device. if the radius of the sphere is 0.5 m, and the density of ammonia is 0.86 kg/m3, what is the mass of the ammonia?

Answers

The mass of the ammonia is equal to 0.215 kilograms.

How to calculate the mass of ammonia?

First of all, we would have to determine the volume of the metal sphere which is half-filled with ammonia. Mathematically, the volume of a sphere can be calculated by using this formula:

Volume = 4/3 × πr³

Where:

r represents the radius.

Substituting the given parameters into the formula, we have;

Volume of metal sphere = 4/3 × 3 × 0.5³

Volume of metal sphere = 4/3 × 3 × 0.125

Volume of metal sphere = 4 × 0.125

Volume of metal sphere = 0.5 cubic meter.

For the volume of ammonia, we have:

Volume of ammonia = 0.5/2

Volume of ammonia = 0.25 cubic meter.

Mathematically, the mass of a substance can be calculated by using this formula:

Mass = Density × Volume

Mass = 0.86 × 0.25

Mass = 0.215 kilograms.

compare the magnitude of the acceleration of the object that you calculate from your measurements to the ""centripetal acceleration"" that you can calculate from the speed and the radius of the object.

Answers

The magnitude of the acceleration of the object that can be calculated from the measurements is compared to the "centripetal acceleration" that can be calculated from the speed and the radius is [tex]a_{c}[/tex] = r ( α t )²

The magnitude of the acceleration of the object that can be calculated the measurements is Angular acceleration. If angular velocity and time are given,

α = ω / t

α = Angular acceleration

ω = Angular velocity

t = Time.

[tex]a_{c}[/tex] = v² / r

[tex]a_{c}[/tex] = Centripetal acceleration

v = Tangential velocity

r = Radius

Rearranging angular acceleration formula as,

ω = α t

v = r ω

[tex]a_{c}[/tex] = v² / r

[tex]a_{c}[/tex] = ( r ω )² / r

[tex]a_{c}[/tex] = r² α² t² / r

[tex]a_{c}[/tex] = r ( α t )²

This is the relation between angular acceleration and centripetal acceleration.

Therefore, the comparison is [tex]a_{c}[/tex] = r ( α t )²
