A 5,000 kg railroad car moving at 3 m/s to the east collides with a 7,500 kg railroad car moving at -2.5 m/s to the west. If the cars couple together,
what type of collision is this? (Extra Credit - Solve for the final velocity of
this collision and include units.) *
10 points

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

conservation of mass

mass before something happens = mass afterwards

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
