Problem
A train starts from rest at a station and moves along a straight track.
(a) Its speed at the end of 20s is 72km/h. Convert this speed into SI units.
(b) Assuming the acceleration of the train is uniform during these 20s, calculate the distance it covers in this time.
(c) Determine the average speed of the train for the same interval and state its value with proper units.
