Question

A bug starts out at rest, 3 m to the right of the origin. It then starts moving on a trip. After 3 s, the bug is seen at 6 m to the right of the origin, travelling at 4 m/s to the right. After 6 s (from the start of the trip), the bug is seen at 4 m to the left of the origin, travelling at 6 m/s to the right.

a.) What is the position vector of the bug 3 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 3 s of the trip?

m/s
d.) What is the average velocity of the bug for the entire trip?

m/s

Explanation / Answer

The last sentence can be ignored.

At 0 seconds the bug is at 3m to the right of the origin.
At 3 seconds the bug is at 6m to the right of the the origin.

Velocity = displacement/time
Velocity = (6m-3m)/3
Velocity = 1.67 m/s to the right.
