(c) [15 points] The "2" subway train 30 from Manhattan to Flatbush Avenue is approaching the nal station (Flatbush Avenue) but has stopped on the tracks somewhere outside of Flatbush Avenue. The graph shows the train's velocity as a function of time, from the point just after it begins to move again, up to the point at which it comes to rest at the Flatbush Avenue station. The positive direction of velocity and displacement is from Manhattan to Time (seconds) Flatbush Avenue along the track. Velocity in miles per haur Give both the magnitude and Sign of each of your numerical answers. (i) What is the train's acceleration from 0 to 10 seconds? And what is its acceleration fron (ii) What is the total displacement of the train from its position at time = zero seconds on Give your answer in meters, using the conversion 1609 meters = 1 mile. (iii) What is the average velocity (in m/s) of the train over the whole 89-second journey in graph
