A hockey player does work on a hockey puck to propel it from rest across the ice. When he applies a constant force over a certain distance, the puck leaves his stick at speed v0 . How much must he increase the distance over which he applies the same force so that the speed of the puck is 2v0

think its the third option

be subject to a force andchange its motion

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
