A box has a weight of 50 N and it is slid along the floor at a constant speed by a force of 25 N as shown. Calculate:?
(i) The friction force.
[Answer: 19.15 N]
(ii) The coefficient of friction between the box and the floor.
[Answer: 0.56]
I do understand that for the first part you can get the Ff by finding x direction force (25cos40=19.15N ) but in second part im really confused. Im finding it hard to grasp the concept of friction. can somebody help

2 AnswersOther - General Health Care10 months agoName of this movie?
Looking for this movie i watched as a child, i dont know its name, or the full plot..
The story line is about some king of an alien invasion of a town and, its residents become possessed by some kind of an alien force, and government agents stay to communicate with them.
one thing I remember specifically is that when the residents are possessed and they try to communicate, all they have to do is open their mouths and words would pour out without their lips moving..
It was an odd movie,, does anybody have any clue what the name is?

Male 26 years old
I stopped Sertraline/zoloft (50mg) a month ago after being on it for 6 weeks.
One day i woke up and my sex drive and excitement (gut feeling) had disappeared so i decided to stop the medication.
i explained it to the doctor and he said that it would come back over time, but its been a month and there is no difference.
if this is going to continue i dont think there is much of point in living anymore since i am a virgin and all my hope were that one day i would meet the girl of my dreams, but i have been stripped off of that!
I am fully numb, no anger, no anxiety, no pain, no motivation and at the moment no will to live if this continues!
does somebody have some kind of an explanation? please i need help and i cant trust the doctors!!
