Describe three forces that are acting in the situation described below

a factory worker carries a box of nails. his shoe slips on a patch of oil on the ground, and he drops the box. the box opens, and the nails all fall to the floor. he uses a powerful magnet to collect all of them and cleans up the oil so no one else slips in it.

1) Force of gravity or weight

2) Friction force

3) Magnetic force

A factory worker is carrying box of nails.

So in this situation of carrying box of nails the worker must applied a force to pull the box against the force of gravity on it. This force is equal to the weight of the nails.

Also for walking on the floor there must be force of friction between his shoes and the floor.

As the friction force becomes very small due to oil drop on floor his shoes slips on the floor and he fell down

Next he used a powerful magnet to collect the nails which falls on the floor so here he used magnetic force to pull all the nails.

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

i would say
