Here are the positions at three different times for a bee in flight(a bee's top speed is about 7 m/s).
time
4.8 s

5.3 s

5.8 s
position
< -3.2,7.7, 0 > m

< -1.0,6.4, 0 > m

< 0.7,4.6, 0 > m

(a) Between 4.8 s and 5.3 s, what was the bee's average velocity? Becareful with signs.
< 4.4correct check mark, -2.6correct check mark, 0 > m/s

(b) Between 4.8 s and 5.8 s, what was the bee's average velocity? Becareful with signs.
< 3.9correct check mark, -3.1correct check mark, 0 > m/s

(c) Of the two average velocities you calculated, which is the bestestimate of the bee's instantaneous velocity at time 4.8 s?
acorrect check mark

(d) Using the best information available, what was the displacementof the bee during the time interval from 4.8 s to 4.85 s?
< -2.98wrong check mark, 7.57wrong check mark, 0 > m

Answer:

(a) see attachment below

(b) see attachment below

(c) the average velocity in part (a) is a better estimate than that in part (b) because it was calculated for a shorter time interval compared to part (b). The basically definition of instantaneous velocity is that it is the limit of the average velocity as the time interview approaches zero (that is as the time interview becomes smaller and smaller). In other words the shorter the time interview the better the accuracy of the result.

(d) see attachment below.
