Question

motorcycle accelerates from rest to a final velocity of 27 m/s in 9 seconds. What is its acceleration?

Answer 1

3 m/s squared

Step-by-step explanation:

The formula you use is Vf= Vi + at. You rearrange it to a= Vf - Vi/t. The Vf is 27m/s. The Vi is 0m/s and the t is 9s. Cross out Vi since it’s zero and you’re left with a= 27m/s divided by 9s, which equals 3
