A wheel moves in the xy plane in such a way that the location of its center is given by the equations xo = 12t3 and yo = R = 2,
Stella [2.4K]

Answer:

the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s  is   P =  104.04 \hat{i} -314.432 \hat{j}

Explanation:

The free-body  diagram below shows the interpretation of the question; from the diagram , the wheel that is rolling in a clockwise directio will have two velocities at point P;

  • the peripheral velocity that is directed downward (-V_y) along the y-axis
  • the linear velocity (V_x) that is directed along the x-axis

Now;

V_x = \frac{d}{dt}(12t^3+2) = 36 t^2

V_x = 36(1.7)^2\\\\V_x = 104.04\ ft/s

Also,

-V_y = R* \omega

where \omega(angular velocity) = \frac{d\theta}{dt} = \frac{d}{dt}(8t^4)

-V_y = 2*32t^3)\\\\\\-V_y = 2*32(1.7^3)\\\\-V_y = 314.432 \ ft/s

∴ the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s  is   P =  104.04 \hat{i} -314.432 \hat{j}

Answer:

1)   Acids have a sour taste.

Acid formulas start with "H", contain hydrogen and some react with active metals in a single replacement reaction to give off hydrogen gas.

An acid will turn blue litmus paper red

All acids are SOLUBLE in water.    

Acids have a pH below 7.

2)     Bases are bitter to taste a bitter taste is characteristic of all bases.

trong bases are very corrosive and can burn the skin.

Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis

They can conduct electricity.

Bases lose their basicity when mixed with acids.

3)    i dont know how to do it on here sorry but its self explanitory!!

4)   0-3 strongly

      4-6 weakly

     7 neutral

      8-10 weakly

      11-14 strongly

hydrochloric acid

lead acid battery

gastric acid

lemon juice
