CBSE ADDA Calculate the average speed of a train, which covers 120 km in 2 hours.Distance covered by the train = 120 km .How far does a car travel in 2.5 h if its average speed is 60 km/h ? .A carriage moves 30 km in one hour. Calculate its speed in m/s. Is it average or uniform speed?  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? Draw the velocity time graph of a body moving with uniform velocity of 5m/s. Write the equation of motion connecting S, u, v and a where the symbols have their usual meanings. What do you infer, if the distance-time graph is a straight line? The distance (S) in meters traveled by a particle is related to time(t) in seconds by the equation of motion . What is the initial velocity of the particle? .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 en...
