2. Conner flips a coin up in the air (to determine if he or his sister needs to do the dishes) at an upward velocity of 4.00 m/s. He fails to catch it on the way down and it falls down an
additional 1.6 m to the floor. Calculate the maximum height and maximum magnitude
(could be positive or negative) velocity of the coin.

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

answerscientific theory;

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
