Question

Please Help Ill Fan and Medal !!!

Two cars, A and B, move along the x-axis. (Figure 1) shows a graph of the positions of A and B versus time. Car A moves with constant acceleration.

Graph velocity versus time for A.
Plot values for velocity at t = 0, 1, 2, 3, and 4 seconds.

Answer 1

Hello!

Answer 2

hi this is the image that goes along with this problem. im not quite sure how to do this one because it is an exponential function

Answer 3

ok....

Answer 4

only Car A is an exponential function, Car B is a linear function...

Answer 5

yeah i know but its asking to graph car A, it also asked about car B but i know how to do that one

Answer 6

I'm stumped. I got an exponential function, but when I graphed it (just in case) it wasn't identical to the one you posted... :(

Answer 7

@kg1975 exponential functions

Answer 8

the graph I posted was the graph of position vs. time I have to make the graph of velocity vs. time which is the derivative of the graph I posted but since I'm not given a function I cant really just derive it, which is why I'm lost

Answer 9

me too... @mathmale
nobody's replying :(

Answer 10

I have to go, sorry I can't help

Answer 11

@steve816 @Kainui @ageta please help

Answer 14

Reminder : position/time = velocity and velocity/time = acceleration

Answer 15

@triciaal The formula to find Velocity it not important for this question

Answer 16

okay but how am I suppose to graph this, where do I start ?

Answer 17

And it is distance/ time

@satellite73 could you help me on this one?
