To find the average velocity of the boat, we need to calculate the displacement and divide it by the time taken.
Displacement = (final position) - (initial position) = 20 meters - 0 meters = 20 meters
Time taken = 18 seconds
Average velocity = Displacement / Time taken
Average velocity = 20 meters / 18 seconds
Average velocity = 1.11 meters per second
Therefore, the correct response is +1.11 m/s.
A speedboat travels from the dock to the first buoy, a distance of 20 meters, in 18 seconds. It began the trip at a speed of 0 meters per second. By the time it reached the buoy, it was going 10 meters per second.
What was the average velocity of the boat?
Responses
−3.33 m/s2
negative 3.33 meters per second squared,
−1.11 m/s
negative 1.11 meters per second,
+1.11 m/s
plus 1.11 meters per second,
+3.33 m/s
