Complete Question

1. What is the linear speed of a point on the edge of a 0.30 m diameter grinding wheel rotating at 1600 rpm?

2. What is the acceleration of the point?

Answer:

1

[tex]v  =  25.14 \  m/s [/tex]

2

[tex]a =  4013.5 \  m/s^2[/tex]

Explanation:

From the question we are told that

    The  diameter is  [tex]d =  0.30 \  m[/tex]

    The  angular speed is  [tex]w =  1600 \  rpm  =  \frac{ 1600 * 2 *  \pi }{60 }  =  167.6 \  rad /s[/tex]

Generally the is mathematically represented as

         [tex]r =  \frac{d}{2}  =  \frac{0.30}{2 }  =  0.15 \  m[/tex]

Generally the linear speed is mathematically represented as

     [tex]v  =  wr[/tex]

     [tex]v  =  167.6 * 0.15[/tex]

      [tex]v  =  25.14 \  m/s [/tex]

Generally the acceleration is mathematically represented as

       [tex]a =  \frac{v^2 }{r}[/tex]

       [tex]a =  \frac{25.14^2}{0.15}[/tex]

         [tex]a =  4013.5 \  m/s^2[/tex]
