As we know that kinetic energy is given as

Here we can find the initial speed of puck A by momentum conservation



now here we will have initial kinetic energy of the mass is given as




now loss of energy is given as

The boiling pot of water is completely open
The P seismic waves travel as elastic motions at the highest speeds. They are longitudinal waves that can be transmitted by both solid and liquid materials in the Earth's interior. With P waves, the particles of the medium vibrate in a manner similar to sound waves—the…
