A train is traveling due north at 80 km/h baseball pitcher stands on the rear platform of the train and throws a baseball due south at 100 km/h to an observer on the ground what is the initial velocity of the baseball

see earlier answer

i think it would be 5

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

the ima (higher than 1m) will be greater than the ima with the height of 1m.
