Acar moving with an initial speed v collides with a second stationary car that is 46.7 percent as massive. after the collision the first car moves in the same direction as before with a speed that is 31.8 percent of the original speed. calculate the final speed of the second car. give your answer in units of the initial speed (i. e. as a fraction of v).

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
