Question

A bird accelerating from rest at a constant rate,experiences a displacement of 28 m in 11s.What is its acceleration

Answer 1

Use the formula below for this question:

$v_{f} = v_{i} + 2 * a * d$

re-arrange to solve for a:

$a = \frac{v_{f} - v_{i}}{2 * d}$

now simply plug in your variables and there's your answer :). If you ever get stuck, you can look up the kinematic equations!
