Cart 1 of mass m is traveling with speed 2vo in the +x-direction when it has an elastic collision with cart 2 of mass 2m traveling with speed vo in the same direction.
What are the velocities of the carts after the collision?
please hurry and answer

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

because growing process had stoped after 4-5 year

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
