Question

A 2400-kg truck accelerates from 18 m/s in 3s. Calculate the average acceleration on the truck.

Answer 1

`\begin{gathered} v1=18\text{ m/s} \\ v2=33\text{ m/s} \\ t=3s \\ a=\text{?} \\ a=(v2-v1)/(t) \\ a=\frac{33\text{ m/s}-18\text{ m/s}}{3s} \\ a=\frac{15\text{ m/s}}{3s} \\ a=5m/s^2 \\ \text{The average acceleration is }5m/s^2 \end{gathered}`
