Question

A train leaves the station heading west on the tracks. It takes the train 8 seconds to reach 80 miles per hour. It completes the entire 160 mile trip in two hours. Calculate the train's average speed and velocity over the two hour trip. Show your work. Identify if Each of the measurements are a scalar or vector quantity.

Answer 1

I figured out the average speed on my own and I know it's measurement is scalar.
But I REALLY REALLY NEED HELP WITH FINDING OUT THE VELOCITY.
I have no idea how.....
but I think it's measurement is vector. (:

Answer 2

Someone help Me? Pretty Pretty Please?

Answer 3

@HelloBriBri how did you find average speed?

Answer 4

I divided distance by time :o

Answer 5

good:D, it comes out as?

Answer 6

which was 2/160 = 80 (:

Answer 7

good, this is average speed.
Velocity also has a direction associated with it, it's going towards west
velocity is 80km/h due west

Answer 8

so my answer on velocity is 80 too? O.O

Answer 9

yeah, 80 km/h due west

Answer 10

and you get it by?
Sorry.....

Answer 11

No problem,
It's mentioned in the question that it travels towards west.
Velocity is the speed of an object and a specification of its direction of motion.
obviously it's a vector

Answer 12

Thank you so much! (:
I'm finally done with this assessment!
That's all that I needed. (:

Answer 13

Great, did you understand?

Answer 14
