Here's the solution to question 4: The problem describes a train's journey with three phases: 1. Acceleration from rest for 150 seconds. 2. Constant speed for 300 seconds. 3. Deceleration to rest for 200 seconds. The total distance travelled is 10450 m. Let V_max be the maximum speed attained. The speed-time graph for this journey is a trapezium. The total distance travelled is the area under this graph. The area can be broken down into three parts: • Area 1 (acceleration phase): A triangle with base 150 s and height V_max. • Area 2 (constant speed
