# Another question! Please if there is anyone good at physics/ engineering here help me out with this :)? thanks?

A car moving with an initial constant velocity covers a 50 m AB span of a highway in 5.0 s. If its velocity at point A is 15.0 m/s, what is its velocity as it passes point B?

the average velocity is 50/5 = 10 m/s

the average velocity is also (A + B) /2 if we can presume a constant acceleration from a to b.

(15+B)/ 2 = 10

15+B = 20

B = 20 - 15 = 5 m/s
