Question

If the velocity of a body changes from 13 m/s to 30 m/s while undergoing constant acceleration, what's the average velocity of the body?

Answer 1

The Correct answer to this question for Penn Foster Students is: 21.5 m/s

Answer 2

Average velocity is found by the following formula:

`v_(average) =  (v_f+v_i)/(2)`

`v_i = 13 \\ v_f = 30 \\ v_(average) =  (30+13)/(2) =  (43)/(2) = 21.5  (m)/(s)`
