A truck of mass 10 metric ton runs at `3ms^(-1)` along a level track and collides with a loaded truck of mass 20 metric ton, standing at rest. If the trucks couple together , the common speed after the collision is

A truck of mass 1200kg is moving with a speed of 7ms^(-1) when it collides with a second truck of mass 1600kg which is stationary. If the two trucks are automatically coupled together on impact, the speed with which combination moves is

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 ?

A block of mass 1 kg moving with a speed of 4 ms^(-1) , collides with another block of mass 2 kg which is at rest. If the lighter block comes to rest after collision, then the speed of the heavier body is

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 truck of mass 15 tons moving with 1 ms^(-1) collides with a stationary truck of mass 10 tons and automatically connected to move together. The common velocity is

A truck of mass 2xx10^(4) kg travelling at 0.5ms^(-1) collides with another truck of half its mass moving in the opposite direction with a velocity of 0.4ms^(-1) . If the trucks couple automatically on collision, calculate the common velocity with which they move.
