Have you looked at the graph ? ?

The weight is at the rest position of the spring and moving upward

when x=6.

During the next 1.5 seconds, it moves up to the upward limit (the

'amplitude' of the oscillation) and then back down to the rest position.

When x=7.5, the weight is back at the spring's rest position, and moving

downward.

**Answer: 942**

**Step-by-step explanation:**

so your d is 300 so your r = 300/2= 150

a=3.14*r*r= 3.14*150*150= 70650

c= 3.14*d= 3.14*300= 942

**Answer:**

D
