A train of 150 m length is going toward north direction at a speed of 10 ms^-1 . A parrot flies at a speed of 5 ms^-1 toward south direction parallel to the railway track. The time taken by the parrot to cross the train is equal to.

A train of 150 m length is going towards north direction at a speed of 10 m/s. A bird flies at a speed of 5 m/s towards south direction paral­lel to the railway track. The time taken by the bird to cross the train is equal to

A 150 m long train is moving in north direction with a velocity of 5m/s and a parrot is also moving in north direction with a velocity of 10 m/s, then find out (i) The time taken by parrot to cross the train (ii) Distance travel by the parrot during the crossing.

A 210 meter long train is moving due north at a of 25 m/s. a small bird is flying due south a little above the train with speed 5 m/s. The time taken by the bird to cross the train is

A particle is moing with a velocity of 10m//s towards east. After 10s its velocity changes to 10m//s towards north. Its average acceleration is:-

A particle is moving eastwards with velocity of 5 m//s . In 10 sec the velocity changes to 5 m//s northwards. The average acceleration in this time is.
