thanks honors student . got 100%
i will also confirm that those answers are correct!
Thank you honors student 100%
Honor student is😸 still 💯 % correct
As of 12/8/2021 honors student is correct. If you are doing the “using vectors to describe momentum quick check” in connexus for tenth grade this is right. Please use honors students answer
an arrow
momentum
...is conserved
6
p = mv
v and p are vectors, denoted by arrows
Force can act with or against the momentum, since it is also a vector (F=ma)
