Question #76195

Answer 1

Distance: `30pi` meters

Displacement: zero meters

Explanation:

-The distance is `2pir` (or `pid` "the circumference") times the number of rounds travelled.

`d` is the diameter which is `15m`, so the distance is the number of rounds (`2`) times the diameter times `pi`

`d=2(15)pi=30pim`

-The displacement is zero meters since the particle has returned to the same point as the original point.
