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 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 movinig 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.

A metal ball of mass 2 kg moving with a velocity of 36km//h has a head on collision with a stationery ball of mass 3 kg. If after the collision, the two balls move together, the loss in kinetic energy dur to collision is

A metal ball of mass 2 kg moving with speed of 36 Km//h has a collision with a stationary ball of mass 3 kg . If ater collision, both the ball move together, the loss in Kinetic energy due to collision is :

A mass of 20 kg moving with a speed of 10 m / s collides with another stationary mass of . 5kg As a result of the collision, the two masses stick together. The kinetic energy of the composite mass will be

A particle of mass 0.1kg moving with an initial speed v collides with another particle of same mass kept at rest. If after collision total energy becomes 0.2J . Then

A particle of mass m moving with speed V collides eleastically with another particle of mass 2mFind speed of smaller mass after head on collision
