Based on your observation of the Tracker videos and the calculations of average vertical velocity and acceleration, Why do you think the vertical acceleration values are not equal to the theoretical acceleration due to gravity, -9.81 meters/second2?
What can you say about your earlier prediction about which ball will land first? If your hypothesis was wrong, can you propose an alternate rationale for the observed results?

answer: (431,2)

step-by-step explanation:

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
