Question

A car starts from rest and speeds up to 30 m/s in a total of 6 s.

What is the acceleration?
ctive
5 m/s2
30 m/s
ker
24 m/s2
5 m/s

Answer 1

5 m/s2

Step-by-step explanation:

Using the equation velocity = initial velocity + (acceleration x time)

30 m/s = 0 + acceleration x 6 s

30 m/s = 6 s x acceleration

30 m/s / 6s = acceleration

acceleration = 5 m/s2
