I mean the road bump one I thought one could figure out. Like the angle would increase the. Max velocity, as would increasing the distance imo. The waves one I had to bash in logic and then draw connections between formulas. Anyone else?
How about MC? Anyone ideas on that?
Yup that’s what I did ikhan4
I failed that lol…we barely did any concepts in my class all year so the multiple choice sucked for me. And I bs the FRQ, but parts of it seemed easy. I think that maybe the only part that I didn’t get on that road bump one was the graph.
@ObitoSigma the practice tests I took were accurate to the real thing. Unfortunately I don’t know where they come from as I did them in class. All I know is my teacher said they were from college board and were “secured documents” so they couldn’t leave the classroom. Last year’s free responses were released so I did them as well.
So glad this test is over! The multiple choice did seem harder than the free response, and I didn’t have to calculate anything for the FR.
I found the MC easier than the FRQ… overall a little easier than the average practice tests I took IMO
I’m pretty sure the distance decreased between the bumps which lowers avg velocity and that’s why the equation didn’t work for part C or whatever
Increasing distance did not increase max velocity- it kept it constant
That was the worst AP test I’ve ever taken…even worse than Chem and World last year. I’ll be so lucky to get a 3. Do you guys think my chances of going to a good college like UCLA are completely ruined? I messed up :((
No they know how hard and new the exam is and there will be a big curve don’t worry
@the_bears18 you’re correct
Why did the distance keep the velocity constant
Why didn’t it? @Wheaties I personally used kinematics laws to show how a greater distance results in a greater final velocity.
It was talking about speed so speed=d/t so if distance were doubled time would be also because it’s the same ramp
The question asked about the max speed
AVERAGE speed equals d/t
And kinematic equations are for constant acceleration idk if that applies here
Oops si daisy. On another note, did the ice or wheel make it down the ramp first? I had no idea I just said the ice
Ice, because all of its energy was converted to translational kinetic, while the wheel was transferred to both rotational kinetic and translational kinetic.
