Question

An object moves backwards from where it starts 100 meters in 20 seconds. What is the velocity of the object?
Select one:

5 m/s2


-5 m/s


5 m/s


- 5 m/s2

Answer 1

5m/s

The formula to find the velocity is distance/time.

So 100/20 is 5m/s.
It’s not 5m/s2 because this is the unit for acceleration.
And it’s not negative because it is not possible for the velocity to be negative.
