Question

The position y(t) of an object is shown in the graph below, where y is measured in feet and t in
minutes. Find the velocity of the object when t = 5.

Answer 1

I found that it was 0/5=0 because someone said it was distance/time so I think the answer is 0

Answer 2

ya.velocity=distance/time.
but when such graph is given we need to find the slope at that point for finding velocity

Answer 3

so I have to divide the slope by the time?

Answer 4

the slope of a line is found by=change in y/change in x
here, y=distance and x=time

Answer 5

x=5
y=2 - That is what the slope is.

Answer 6

consider any 2 points on that line and then find the slope=(y2-y1)/(x2-x1)

Answer 7

am I just finding the slope and that will be the answer?

Answer 8

yup

Answer 9

So will the slope be negative?

Answer 10

yes.in this case it indicates velocity in the opposite direction
