Homework Answers
Distance is V x t = but 30 is in seconds.
30 seconds x 1 min/60 seconds x 1 hr/60 min = 0.0083 hr
Distance = 37.5 x 0.0083 = .312 km < ========= Ans

The diagram below shows the speed time graph for a train travelling between two stations
The diagram below shows the speed time graph for a train travelling between two stations. The train starts from rest and accelerates uniformly for 150 seconds. It then travels at a constant speed for 300 seconds and finally decelerates uniformly for 200 seconds. Fig.Given that the distance between the two stations is 10 450m, calculate the:(a) maximum speed, in km/h, the train attained;(b) acceleration;(c) distance the train traveled during the last 100 seconds(d) time the train takes to travel the...
