At [tex]t = 3[/tex], the particle will be at rest for the position along the x- axis which has been given as [tex]v(t) = t^{2} -3t^{2} -9t[/tex].

What do we mean by particle at rest?

You could understand the phrase "A particle at rest tends to stay at rest" to mean that a particle that is not moving relative to some reference objects tends to remain stationary relative to those same things.

The particle is at rest when velocity of the particle is [tex]0[/tex]. From this we know that the velocity is [tex]v(t) = t^{2} -3t^{2} -9t[/tex]

Therefore the velocity is [tex]0[/tex] when [tex]t[/tex] is

[tex]t^{3} -3t^{2} -9t = 0[/tex]

[tex]t( t^{2} -3t -9)[/tex] [tex]= 0[/tex]

[tex]( t^{2} -3t -9) = 0[/tex]

[tex]t^{2} -3t -3t -9 = 0[/tex]

[tex]t(t -3)-3(t -3) = 0[/tex]

The angular velocity of the pointed rim of a rotating wheel if, The angular position of a point on the rim of a rotating wheel is given by θ = 4.0 t - 3.0 t² + t³, is 4 rad/ sec.

The rotation rate, which refers to how quickly an item rotates or circles in relation to another point, is measured pictorially by angular velocity. Angular velocity can be defined as the speed at which an item rotates or revolves around an axis.

Given:

θ = 4.0 t - 3.0 t² + t³

Calculate the angular velocity by differentiating the position function as shown below,

dθ / dt = d (4.0 t - 3.0 t² + t³) / dt

V = 4.0 - 6t + 3t²   (Change in position is equal to velocity)

Put the value of time, t = 2

V = 4 - 6 × 2 + 3 × 2²

V = 4 - 12 + 3 × 4

V = 4 - 12 + 12

V = 4 rad/sec

Thus, the angular velocity is 4 rad/sec.

Answer:

I would assume that the big loaded truck driving on the freeway would have more momentum and push the baseball sized meteorite backwards. This is because the truck is much larger and heavier than the meteorite, and it is also moving at a much higher speed. The momentum of an object is directly proportional to its mass and velocity, so the truck would have a much greater momentum than the meteorite. Additionally, the truck is moving on a solid surface (the freeway) while the meteorite is moving through the air, which would also affect its momentum. However, this is just an assumption based on the information given, and the actual outcome would depend on many factors, such as the exact speed and mass of the truck and meteorite, the angle and direction of their motion, and any other forces that may be acting on them.

Explanation:

Answer:

Explanation:

I'm going to guess the big truck.  

The truck does have a lot more mass, while the meteorite has a lot more speed.

p = mv

mass of truck = 5,000 kg , mass of meteorite = 1 kg  ( it could be a metal)

truck has 5,000 times mass

velocity of meteorite 213,000 km/h ( as it enters atmosphere) ,  truck 55 km/h

3900 times more velocity

The truck wins.  

Also, by the time the meteorite gets to the ground it will have slowed down considerably.   Ofc,  the truck will be on the ground.  

Answer:

a + b = c      where a and b and c are vector quantities

Since c is the result of adding vector b to vector a (to add two vectors the vectors are connected head to tail)

a^2 + b^2 - 2 ab cos θ = c^2 is an expression of such a relationship

Note that a^2 + b^2 = c^2 if a and b are at right angles to one another

Another way to express this is:

a x + b x = c x    where a and b are the x-components of a and b

a y + b y = c y      describes the y -components of a and b

The above two equations will provide the x and y components of vector c

To find the magnitude of a force vector that is 3 cm by 5 cm, you would use the formula:

magnitude = [tex]sqrt(3^2 + 5^2) = sqrt(9 + 25) = sqrt(34) = 5.8[/tex]

1 cm = 21 N, you would multiply the magnitude by 21:

[tex]intensity = magnitude * 21 = 5.8 * 21 = 121.8 n[/tex]

A force vector is a physical quantity that represents a force acting on an object. It has both magnitude and direction, and it is represented graphically by an arrow with a length proportional to its magnitude and an orientation that shows its direction.

For example, if you push a book across a table, the force you apply to the book is a force vector. It has a certain magnitude (e.g. 10 newtons), and it is directed from your hand towards the book.

Force vectors are important in physics because they allow us to analyze the forces acting on an object and predict how the object will move in response to those forces. In order to do this, we can use vector addition, which allows us to add multiple force vectors together to find the net force acting on an object.

Planet that the person is standing on is Earth. However, it is also possible that the person is standing on a planet or moon with a similar acceleration due to gravity.

The weight of an object is the force exerted on it by gravity, and it is equal to the mass of the object multiplied by the acceleration due to gravity. The acceleration due to gravity is a measure of the strength of the gravitational field at a particular location, and it is denoted by the symbol g.

The weight of an object can be calculated using the equation:

Weight = Mass * g

In this case, the person has a mass of 35.0 kg and a weight of 343 N. To determine the acceleration due to gravity at the location where the person is standing, we can rearrange the equation above to solve for g:

g = Weight / Mass

Plugging in the values given, we get:

g = 343 N / 35.0 kg

This simplifies to:

g = 9.8 m/s^2

This table shows the acceleration due to gravity on four different planets what planet is a person standing on if the person has a mass of 85.0 kg and weighs 305 N mercury is 3.59 Venus 8.87 Earth 9.81 mars 3.77

The force with which the track pushes on the shell at point A is F = 2/3 m g.

In part (c), 1/2 m v² = m g h₀ - 2 m g R

v² = 2 g h₀ - 4 g R

v² = 2 g (17 R/6 ) - 4 g R
