\fB. Now let's think about 1What controls the response time. First, imagine the effect of changing the massless springs. . Suppose each of the massless springs in the model were suddenly made stiffer (harder to stretch]. Would the increased stiffness increase or decrease the response time? 1|Why? 2. So, would stiffening the massless springs increase or decrease the pulse speed? 3. Hou-r does the answer you just gave compare with your reasoning in section IL part A above (back on page 2}? Explain. C. Now let's think about how the masses in our model affect the response time and pulse speed. Suppose each of the masses were made biggerI but the massless springs were left unchanged. 1. Would this increase or decrease the response time1 or would the response time be unaffected? Explain. 2. So, would increasing those masses make the pulse travel faster or slower? 3. Does the answer you just gave mesh with your reasoning in section II {page 2] above
