Question

The $160-\mathrm{Mg}$ train travels with a speed of $80 \mathrm{~km} / \mathrm{h}$ when it starts to climb the slope $\left(\tan\theta = \frac{1}{10}\right)$. If the engine exerts a traction force $\mathbf{F}$ of $1 / 20$ of the weight of the train and the rolling resistance $\mathbf{F}_D$ is equal to $1 / 500$ of the weight of the train, determine the deceleration of the train.
