The problem refers to a speed-time graph, which is not provided. I will infer the characteristics of the graph based on the questions and the student's partial solution for part (a). Part (a): Retardation of the particle in the first 10 seconds. The student's work shows: a = (u - v)/(t) a = (0 - 15)/(10) a = (15)/(10) a = 1.5 m/s^2 The formula for acceleration is a = (v - u)/(t). Retardation is negative acceleration, meaning speed
