5. A body starts from rest and accelerates at 3 m s² for 4 s. Its velocity remains constant at the maximum value so reached for 7 s and finally comes to rest with uniform negative acceleration after another 5s. Use a graphical method to find each of the following: (a) the distance moved during each stage of motion, (b) the average velocity over the whole period.
To solve this problem using graphical methods, we can plot the velocity-time graph and use the area under the curve to find the distance moved during each stage of motion. Let's break down the problem step by step
