This is a logic puzzle which requires students to use their understanding of the algebra involved in Newton's 2nd Law of Motion (F = ma) to solve correctly. The masses and acceleration are given but not attributed to a particular student, and the instructions are to help the students figure out the masses of each of the carts, the acceleration of each of the carts and the force applied to each of the carts. There are five sets of each piece (Force, mass, acceleration) of data. I use this as a fun wrap-up of Newton's 2nd Law of Motion with my 9th grade physics and 9th grade physical science classes.
I don't think the logic puzzle can work.
The masses have to be (top to bottom): 9, 4.5, 6, 10, 12 based on the 1st three clues. This means clue 7 can't be fulfilled; also, clue 4 and 9 can't be simultaneously true.
I stopped there but I would imagine there are other contradictions as well.
A great idea and thanks so much for sharing for free, but it needs some work!
The masses top to bottom are 6, 4.5, 12, 9, & 10. This fulfills the first three clues. If the masses were as stated above (9, 4.5, 6, 10, & 12), then the first clue (Karla's cart's mass is 50% less than Daneisha's) couldn't be true..
I appreciate the feedback, please let me know if you see other things that seem at odds with the clues. :)
I am sure your students enjoy using what they have learned to solve the logic puzzle. Your "Newton's 2nd Law of Motion, F=ma, Logic Puzzle" was the featured "Free Lesson of the Day" on "The Best of Teachers Pay Teachers."
Hope you are having a great school year,
