1) Calculate the average speed of a train, which covers 120 km in 2 hours. Distance covered by the train =
120 km
2) How far does a car travel in 2.5 h if its average speed is 60 km/h ?
3) A carriage moves 30 km in one hour. Calculate its speed in m/s. Is it average or uniform speed?
4) You are asked to run in a straight line. If you cover a distance of 5 m in each second, what is your (a)
speed (b) velocity?
5) Write the equation of motion connecting S, u, v and a where the symbols have their usual meanings.
6) On a 60 km track, a train travels the first 30 km at a uniform speed of 30 km/h. How fast must the train
travel the next 30 km so that the average speed is 40 km/h for the entire trip?
7) A train travels a distance with a speed of 30 km/h and returns with a speed of 50 km/h. Calculate the
average speed of the train.
8) Find the initial velocity of a train, which is stopped in 25 seconds. The retardation produced in the train is
1.5 m/s.
