How much work would it take to lift it up a distance of 3 meters?
What is the magnitude of the force required to push the block of ice up the incline?
How much work is required to push the block of ice up the incline?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow

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

well clustered together.
