A railway carriage of mass 9000kg moving with a speed of `36kmh^(-1)` collides with a stationary carriage of the same mass. After the collision, the two get coupled and move together. What is this common speed ? What type of collision is this?

A railway carriage of mass 9000 kg moving with a speed of 36kmh^(-1) collides with a stationary carriage of same mass. After the collision, the carriages get coupled and move together. What is their common speed after collision? What type of collision is this?

A railway carriage of mass 9,000 kg moving with a speed of 36 km h^-1 strikes a stationary carriage of same mass. After the collision, the carriages get coupled and move together. what is their common speed after collision? Is the collision elastic?

A truck of mass 1000 kg moving with a speed of 72 km/hr collides with a stationary truck of the same mass . After the collision , the trucks get stick together and move . Calculate their common speed after collision . Is it elastic or ineleastic collision ?

The mass of the railway carriage is 8000 kg which is moving with the speed of 54 km h^(-1) collides with the another stationary carriage of same mass. Determine the loss in kinetic energy in this process.
