1. A train leaves the station on a 50 km commute. The train must make a 60-second stopevery 1.0 km to pick up and drop off passengers. The train accelerates at 2.0 m/s2, then cruises at90 km/h, and then decelerates at 5.0 m/s2 between stops.(a.} How many stops does the train make?(b.} How long does it take for the train to get from one stop to the next?(c.} What is the total time for the entire commute?

10. A person is driving along a straight highway at a speed of 22.0 m/s when the traffic light which is 41.0 m ahead turns yellow. Because of his "reaction time", there is a delay of 0.11 s before the man steps on the brake. The car then slows with a deceleration of 4.40 m/s2. By how much distance does the driver miss the traffic light line? 50 ssi sf60 sf60 60 ssf60%
