Complete Question

The complete question is shown on the first uploaded image  

Answer:

a

 a_{max} = 0.00246 \  m/s^2

b

   k  =722.2 \ N/m

Explanation:

From the question we are told that

     The  amplitude is A  = 1.8 \ cm  =  0.018 \ m

     The period is T  = 17 \ s

    The test weight is  W =  13 \ N

Generally the radial acceleration is mathematically represented as

        a =  w^2 r

at maximum angular acceleration

       r =  A

So  

       a_{max} =  w^2 A

Now w is the angular velocity which is mathematically represented as

      w =  \frac{2 * \pi }{T}

Therefore

       a_{max} =  [\frac{2 *  \pi}{T} ]^2 * A

substituting values

       a_{max} =  [\frac{2 *  3.142}{17} ]^2 * 0.018

       a_{max} = 0.00246 \  m/s^2

Generally this test weight is mathematically represented as

     W =  k *  A

Where k is the spring constant

Therefore

        k  = \frac{W}{A}

substituting values        

      k  = \frac{13}{0.018}

     k  =722.2 \ N/m
