A bug starts out at rest, 4 m to the right of the origin. It then starts moving on a trip. After 1 s, the bug is seen at 9 m to the right of the origin, travelling at 8 m/s to the right. After 4 s (from the start of the trip), the bug is seen at 2 m to the left of the origin, travelling at 4 m/s to the right.

a.) What is the position vector of the bug 1 s after the start of the trip? m
b.) What is the displacement vector of the bug for the entire trip? m
c.) What is the average velocity of the bug for the first 1 s of the trip? m/s
d.) What is the average velocity of the bug for the entire trip?
