A bottle of pills travels on a conveyer belt at a constant
speed, and in a horizontal plane. The figure below shows a portion
of the conveyer belt, and the path traveled by the pill bottle, as
viewed looking down from above. The pill bottle’s trip on the
conveyer belt contains 3 straight segments: one between the points
1 and 2, another between points 4 and 5, and a third straight
segment between points 7 and 8. Each of those segments has a length
of 6.00 m, as shown in the figure. The semi-circular segments of
the conveyer belt (also shown in the figure) have the same radius R
= 1.50 m. It takes the pill bottle 10.0 seconds to travel along
each of the straight segments of the conveyer belt. 1. How much
time does it take the pill bottle to travel along one of the
semi-circular portions of the track? A. 62.8 sec. B. 7.85 sec. C.

from point “1" to point “8", the pill bottle ’s average speed is A.

the semi-circle from point “5" to point “7", the pill bottle ’s
