Gabe throws a tennis ball up into the air with an initial velocity of +22.0 m/s a. How far up will the tennis ball fly

b. What is the total time the tennis ball will be in the air ?

c. What is the tennis balls velocity when it is halfway up its path ?

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
