An object at rest requires a force of 15 newtons to set it into motion

The force that required an object to move is greater than friction force. The opposite force for an object in motion is the friction force (assuming that the surface where the object lies is rough as most real objects are). This force is needed to be overcome to set the object to motion.

Explanation:

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

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
