Question

hi , i am having a lot of trouble with this problem any help would be appreciated A little cat, Bella, walks in a straight line, which we shall call the x axis, with the positive direction to the right. As an observant scientist, you make measurements of her motion and construct a graph of the little feline's velocity as a function of time. Find the x component of Bella's velocity at t = 4.00 s. give me a sec have to draw graph...

Answer 1

to see the graph i found the question online here it is http://www.cobaltss.net/forums/lounge-42/anyone-good-physics-151699/

Answer 2

\[v(t)=\frac{-4}{3}t+8\]

Answer 3

\[a(t)=\frac{-4}3{}\]

Answer 4

a) t=4
v(t)=-16/3+8
v(t=4)=2.66

Answer 5

can you please explain to me what the question is asking

Answer 6

i mean how did you figure out the first equation you wrote

Answer 7

ok, the line is passing (0,8) and (6,0) right

Answer 8

yah

Answer 9

and we know its slope is -8/6

Answer 10

yah

Answer 11

y=mx+n

its formula

Answer 12

okay

Answer 13

put m=-8/6
and (0,8) or (6,0) to find n

Answer 14

y=-8/6x+8=-4/3+8

Answer 15

y=V(t)
x=t

Answer 16

so this is how find the velocity
