A train takes 2 minutes to acquire its full speed 60 kph from rest and 1 minute to come to rest from the full speed. If some where in between two stations 1 km of the track be under repair and the limited speed on this part be fixed to 20 kph, find the late running of the train on account of this repair work, assuming otherwise normal at running of the train between the stations.

A particle travels with constant speed along a circle of radius 3m and completes one revolution in 20s. Starting with the lowest point as origin ,
find (a) the magnitude and direction of the displacement vectors 5 s ,
Two trains ,
Two trains, each with a speed of 50 kmph are headed towards each other on the same trake. A bird that can fly at the rate of 100kmph flies off one train when they are 100km apart and heads directly to the other train. On reaching the other train it flies back to the first train and so forth. (a) How many trips can the bird make from one train to the other before they crash ? (b) How is the total distance the bird travels ?
