Two objects are dropped from rest from the same height. object a falls through a distance da and during a time t, and object b falls through a distance db during a time 2t. if air resistance is negligible, what is the relationship between da and db? da=1/4dbit cannot be determined from the information given. da=4dbda=2dbda=1/2db

Da=(1/4)Db

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration due to gravity = 9.81 m/s²

When s = Da, t = t

When s = Db, t = 2t

Dividing the two equations

Hence, Da=(1/4)Db

im guessing the west of station b

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
