Question

A cyclist rolls down a hill. He starts from rest and after 8 s he is traveling at 13.6m/s. What is his acceleration?

Answer 1

1.7 m/s^2

Explanation

acceleration is change in velocity / time

so we do 13.6 - 0 = 13.6 gives us change in velocity

13.6/8 = 1.7 m/s^2 gives acceleration

hope this helps
