Question

If a car's velocity increases to 30 m/s from rest in 6 s, what is its acceleration? QUESTION - What is the variable Vf equal to? ​

Answer 1

Answer:

Explanation:

The car is going from v = 0 m/s to v = 30 m/s

I'm going to make a pretty sure bet that Vf = 30

a = Δv/t = (vf - vi)/t = (30 - 0) / 6 = 5 m/s²
