Homework Statement
This is the v-t(velocity-time) graph of two moving objects,A and B :
Please check whether the following statement is true or false(including wrong description).
At the moment t1, the acceleration of A is BIGGER than that of B.
PS: In this case,"a vector A is bigger than another one B" means ||A||>||B||.
Homework Equations
The Attempt at a Solution
I'm a Chinese senior high school student who is not good at English,so please don't mind mistakes of grammar.I am really trying my best to post this thread.:shy::shy:
I think this statement is right,but my teacher said that there's no given exact numbers or function expressions and we can't find the exact relationship between line A and line B,including their point of intersection.
My opinion is that we can find the answer from the graph obviously( considering a very short range covering the point t1, delta(v) of A is obviously bigger than that of B )
Thank in advance!
