A bee is making a beeline for its hive. Its velocity is measured at a distance of 75 meters from the observer and again at distance 145 meters from the observer. The clock times at these two positions are t = 9 sec and t = 16 sec, and the measured velocities are 3 m/sec and 13.5 m/sec. What is its average velocity during this time? What is its average acceleration during this time? Is it possible that the acceleration is uniform?

‘ds = 145m-75m= 70m; ‘dt =16s-9s=7s; ‘dv=13.5m/s-3m/s=10.5m/s

vAve= 70m/7s= 10m/s; aAve=(10.5m/s)/7s= 1.5m/s^2

yes it is possible that the average acceleration is uniform as long as the velocity continuously increased at constant rate.

If acceleration is uniform, then the v vs. t graph is linear, from which it follows that the average velocity is the average of initial and final velocities.

Is that the case here?

What do you conclude?
