Two balls of the same size but different matetials, rubber and iron are kept on the smooth floor of a moving train. The brakers are applied suddenly to stop the train . Will the balls start rolling? If so, in which direction? Will they move with the same speed? Give reasons for your answers.

To solve the question about the two balls (rubber and iron) on a moving train when the brakes are applied, we can break it down into several steps: ### Step 1: Understand the Situation The train is moving at a certain speed, and both balls (rubber and iron) are at rest relative to the train. When the brakes are applied suddenly, the train will decelerate and eventually stop. **Hint:** Consider the concept of inertia and how it applies to objects in motion. ### Step 2: Apply Newton's First Law of Motion ...

Two trains, which are moving along different tracks in opposite directions, are put on the same track due to a mistake. Their drivers, on noticing the mistake, start slowing down the trains when the trains are 300 m apart. Graphs given in figure show their velocities as function of time as the trains slow down. The separation between the trains when both have stopped is

In the figure the top view of a compartment of a train is shown. A man is sitting at a corner 'B' of the compartment . The man throws a ball ( with respect to himself ) along the surface of the floor towards the corner 'D' of the compartment of the train. The ball hits the corner 'A' of the compartment, then find the time at which it hits A after the ball is thrown . Assume no other collision during motion and floor is smooth. The length of the compartment is given 'l' and the train is moving with constant acceleration 'a' in the direction shown in the figure.

A train starting from rest is moving along a straight track with a constant acceleration fo 2.5m//s^(2) . A passenger at rest in the train observes a particle of mass 2kg to be at rest on the floor with which it has a coefficient of friction mu_(s) = mu_(k) = 0.5 .Six seconds after the starting of the train , a horizontal force F = 13N is applied to the particle for two seconds duration. The passenger now observes the particle to move perpendicular to the direction of the train. (a) calculate the kinetic energy of the particle with respect to the passenger at the end of 8 seconds after starting of the train. ( b) repeat the calculate of ( a) for an observer on the ground.
