This is from the physics book for BR
Basically it is a problem where a mass is pushed up an air track.
"For experiment 2, in the case where the total transit time is 6 seconds
and the distance the air cart travels up the air track is 11.25 meters,
what is the average speed for the entire motion?"
Now, the experiment in context is not important. A mass is pushed up an air track and falls down. NOTE and ALL of the data values for the mass are only of it traveling UP. Again, TRAVELING UP... the experiment doesn't even say how long the track is
But apparently the answer to this question is 3.75 m/s (The total for if the car as it goes up the track and comes back down).
What the heck??
How in the world am I supposed to know that this problem is for the mass going up AND down??
This has to be a bad question, I can't think of any reason "Entire motion" would signify going up and down the track, when all the data given is only for the up...
