A train is moving slowly at 2 m/s next to a railway platform. A man, 15 m tall, alights from the train such that his feet are fixed on the ground. Taking him to be a rigid body, the instantaneous angular velocity (in rad/sec)is

A body A is Placed on a railway platform and an identical body B in a moving train. Which of the following energies of B are greater than those of A as seen from the ground?

An engine of a train is moving towards a platform with a velocity of 100 m s^(-1) . If the frequency of sound produced is 200 Hz , find the apparent frequency of the sound as observed by an observer standing on the platform (Taking velocity of sound = 320 m s^(-1) ) .

A train is moving towards East with a speed 20 m/s. A person is running on the roof of the train with a speed 3 m/s against the motion of train. Velocity of the person as seen by an observer on ground will be :

Priya is sitting on the edge of a horizontal circular platform of radius 6m rotating with constant angular velocity and Rahul is standing still on the ground at a point 12m from the center of platform. At a particular instant rahul observes that priya is moving directly towards him with a speed of 1m/s .Then at the same instant :-

A train 110 m long takes three seconds to pass a standing man. How long is the platform if the train passes through it in 15 seconds moving with the same speed?

A body of mass 10 kg is moving in a circle of radian 1 m with an angular velocity of 2 rad//s the centripetal force is

Two trains are moving towards each other at speeds of 20 m/s and 15 m/s relative to the ground. The first train sounds a whistle of frequency 600 Hz . the frequency of the whistle heard by a passenger in the second train before the train meets is (the speed of sound in air is 340 m/s )

A train moving on a 1.5 m wide track takes a curve of radius 400 m. To make it happen, height by which outer rail should be raised? (Velocity of train was given in real paper)

A man standing on a railway platform noteced that a train took 21 secods to cross the platform (this means the time elpsed from the moment the engine enthers the the platform till the last compartment leaves the platform ) which is 88 meters long and that it took 9 seconds to pass him ,ASsuming that the train was moving with unform speed , what is the langth of the train in meters ?

A body is dropped from a balloon moving up with a velocity of 4 m//s , when the balloon is at a height of 120 m from the ground. The height of the body after 5 s from the ground is:
