Question

A car accelerates from 12m/s to 18m/s in 6.0 seconds. How far did it travel in this time?

Answer 1

Hello! Do you understand the situation?

Answer 2

Im not completely sure about it

Answer 3

Okay! Do you like working with pictures more, or numbers?

Answer 4

numbers

Answer 5

Okay!

Well, which quantities do we have?

Answer 6

m/s, distance

Answer 7

initial velocity, final velocity, and time are what we have, and we need that distance! :)

Answer 8

So, can you think of any equations for distance?

Answer 9

X2-X1

Answer 10

That's not an equation, though! Equations have equal signs, and say that two things are equal!

Answer 11

delta change in x=X2-X1

Answer 12

I was going for
\(\Delta x=v_it+\dfrac12at^2\)

You can solve for \(a\), by it's definition.
