To solve the problem, we will follow these steps: ### Step 1: Understand the problem We are given that a car changes its velocity from \(10 \, \text{m/s}\) to \(20 \, \text{m/s}\) over a time period of \(5\) seconds. We need to plot a velocity-time (v-t) graph and derive the equation for velocity as a function of time. ### Step 2: Calculate the slope of the v-t graph The slope \(m\) of a linear graph is calculated as: \[ ...
