Answer:
0.23 s.
Explanation:
Let’s investigate the given positions.
We are asked to find the time it takes from x = 0 to x = -A. The part goes in the +x direction, so it will first go +A, then it turns back and goes to -A. The time it takes for this trajectory is 3T/4, where T is the period.
T = 1/f = 0.3125.
So the time it takes from x = 0 to x = -A is 0.23 s.
