Question

A car travels in a straight line at 90.0 m/s for 1000 m and then travels at 60.0 m/s for the next 1000 m. What is the average velocity?

Answer 1

I want you to know Khanacademy.org is a good website and will explain everything here is a link https://www.khanacademy.org/science/physics/one-dimensional-motion/displacement-velocity-time/v/calculating-average-velocity-or-speed to your question

Answer 2

@caneschik05 I hope it helps!

Answer 3

Are you good? @caneschik05

Answer 4

Hello?

Answer 5

We know that the car travelled a total of 2000m. We just need to know the time it took to travel this distance.

How long did it take to travel the first 1000m?

When given a distance and a speed, we can find the time by:
\[Time = \frac{Distance}{Speed}\]

Answer 6

Whoever gave me the medal thanks!

Answer 7

Thank you fo explaining the problem out cause I couldn't I had to do something

Answer 8

I'm still not sure how to solve this because the problem he did was already given the time.

Answer 9

Nevermind I figured it out, thank you!

Answer 10

Ok!

Answer 11

Average speed equals total distance upon total time.
Total distance is 2000 m
Total time is (1000/90)+(1000/60) that is (15/54)
Therefor average speed equals 72 m/s
