Abumper car with a mass of 250 kg is traveling at a speed of 4 m/s. this bumper car collides and sticks to a second bumper car with a mass of 250 kg, which is initially at rest. what is the final speed of these two bumper cars after the collision, assuming they remain stuck together?
Here in this type of collision problem we can say that there is no external force on the system of two cars
So we can use the momentum conservation in this
here we have
now from above equation we will have
so both cars will move together with speed 2 m/s
the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
