As a science project, you drop a watermelon off the top of the empire state building, 320 m above the sidewalk. it so happens that superman flies by at the instant you release the watermelon. superman is headed straight down with a speed of 24 m/s. how fast is the watermelon going when it passes superman?

47.9709 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

For watermelon

For superman

The distance travelled by the watermelon and superman will be same

The watermelon is going at a speed of 47.9709 m/s when it passes Superman

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
