Timer Notes à Evaluate Feedback Matching Graphs Due on Friday, Sep 14 at 11:59 pm (EDT) discussed. The origin of each plot is represented by O, and the function is represented by the colored line You hold your arm out over a cliff and release a rock from rest.Consider the time from just after the rock leaves your hand to just before it hits the ground. which graph best represents the position of the rock as a function of time? (Choose up to be the positive direction and choose the point the stone is released as the origin.) n B You throw a stone straight up, and it falls back into your hand. Consider the time from just after the stone leaves your hand to just before it hits your hand coming back the acceleration of the stone as a function of time? (Choose up to be the positive direction.) A van is driving West at a constant velocity. Which graph best represents the velocity of the van as a function of time o B A car starts from rest at a stoplight and undergoes constant acceleration to the East. Which graph best represents the velocity of the car as a of time? (Choose East to be the positive direction) Send This discussion is closed

Explanation / Answer

the first question has wrong answer.

It should be H because. at t=0 stone at origin position

and after releasing, it distance increase nonlinearly (S = ut + 0.5at2) with time in downward direction

So the answer is H

all other answers are correct.
