HURRY PLS 30 MINS LEFT A ball is rolling across the floor so that it is traveling along the positive x axis at 5.00 m/s. Due to the bend of the carpet fibers it experiences an acceleration of 1.25 m/s2 at an angle of -125.0o from the x axis.

A. What is the x component of the acceleration?

B. What is the y component of the acceleration?

C. What is the x component of the balls displacement after 3.00s?

D. What is the y component of the balls displacement after 3.00s?

E. What is the displacement of the ball over 3.00s?

A) aₓ = -0.717 m / s² ,  B)  a_{y} = -1.024 m / s², C) x = 11.77 m , D) y = -4.6 m ,

E)  d = 12.64 m

Explanation:

For this exercise we will use trigonometry to decompose the acceleration, we are told that

   a = 1.25 m /s²   with an angle tea = 125º in a clockwise direction

A) cos θ = aₓ / a

       aₓ = a cos θ

       aₓ = 1.25 cos (-125)

       aₓ = -0.717 m / s²

B)  sin θ = / a

     a_{y} = a sin θ

     a_{y} = 1.25 sin (-125)

    a_{y} = -1.024 m / s²

C) The displacement component

     x = v₀ₓ t + ½ aₓ t²

let's calculate

      x = 5 3 + ½ (-0.717) 3²

      x = 11.77 m

D) the y component of the displacement

      y = t + ½ t²

in this case the initial velocity is zero

      y = 0 + ½ (-1,024) 3²

      y = -4.6 m

E) Let's use the Pythagorean theorem

     d =√ (x² + y²)

     d = √ (11.77² + 4.6²)

     d = 12.64 m

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
