A particle moves horizontally in uniform circular motion, over a horizontal xy plane. At one instant, it moves through the point at coordinates (3.20 m, 3.50 m) with a velocity of –2.50 i^ m/s and an acceleration of +11.6 j^ m/s2. What are the (a) x and (b) y coordinates of the center of the circular path?

Respuesta :

since centripetal acceleration is always towards the center of the circle

so at the given position where speed and acceleration is given the center coordinate will be towards the center of circle

also we know that

[tex]a_c = \frac{v^2}{r}[/tex]

[tex]11.6 = \frac{2.5^2}{R}[/tex]

[tex]R = 0.54 m[/tex]

so the coordinates of the center will be

[tex](x, y) = (3.20 , (3.5 + 0.54))[/tex]

[tex](x, y) = (3.20, 4.04)[/tex]

so the coordinate is (3.20 m, 4.04 m)

We have that for the Question " the(a) x and y coordinates of the center of the circular path" it can be said that the x and y ordinates are

  • x-component = 4.60 m
  • y-component = 4.05 m

From the question we are told

  • A particle moves horizontally in uniform circular motion, over a horizontal xy plane.
  • At one instant, it moves through the point at coordinates (3.20 m, 3.50 m) with a velocity of –2.50 i^ m/s and an acceleration of +11.6 j^ m/s2. What are the
  • (a) x and
  • (b) y coordinates of the center of the circular path?

x and y coordinates

Generally the equation for the  Acceleration is mathematically given as

[tex]a = \frac{v^2}[r}\\\\Therefore\\\\r= \frac{3.2^2}{10.8}\\\\r=0.95 m[/tex]

Hence

We have the center at

C= (4.60, (0.95 + 3.10))

C= (4.60, 4.05)

Therefore

  • x-component = 4.60 m
  • y-component = 4.05 m
