Question

A stopped car begins moving and reaches a speed of

25m/s in 5 seconds. What is its acceleration?

+25m/s2
+5m/s2
-Om/s²
5m/s

Answer 1

B) 5m/s^2

Step-by-step explanation:

The formula for acceleration is
`(vf-vi)/(t)`

vf is the final velocity which in this question is 25m/s

vi is the initial velocity which in this question in 0m/s because it says "A stopped car"

t is the time which is 5 seconds

When you put these numbers into the formula you get 5m/s^2
