Perfect! Jerry's final velocity was \(5 \, \mathrm{m/s}\). His initial velocity was \(2.5 \, \mathrm{m/s}\). So, the change in velocity is \(\left(5 - 2.5\right) \, \mathrm{m/s}\), and it takes \(2 \, \mathrm{s}\) for that change. So, the acceleration is \(\frac{5 - 2.5}{2}\).
Hopefully, by now you are familiar with concepts of displacement, velocity and acceleration. In the next module, we will use equations to solve for these quantities. See you there!
