Acceleration
Sample Problems
- Calculate the acceleration of a car that starts from rest to a velocity of 23 m/s in 15 s.
- vi = 0 m/s
- vf = 23 m/s
- ti = 0 s
- tf = 15 s
- a = ?
Given
- Solution
\[
\begin{align*}
\vec{a} &= \frac{v_f - v_i}{t_f - t_i} \\
&= \frac{23\, \text{m/s} - 0\, \text{m/s}}{15\, \text{s} - 0\, \text{s}} \\
&= 1.53\, \text{m/s}^2
\end{align*}
\]
