Question

PLEASE HELP WILL GIVE BRALIEST

12. A bird flies 10 m in 2 seconds. What is its speed?


13. A plane takes 8 hours to fly 5000 km. What is its speed?


14. When given a motion graph, how can you tell if it’s a speed graph or acceleration graph?

Answer 1

12: If the bird flies 10m in 2s, it's speed is then 10m/2s, which we can simplify giving us 5m/s

13: Flying 5000 km in eight hours means that it's flying at (5000 / 8)km/h, or 625km/h

14: A speed graph will not go below zero, an acceleration graph will.
