Salut, répondre m'a question
A body of mass 5kg starts and rolls down 32m of an inclined plane in 4s . Find the force acting on the body
Iloveanime:
ces't vraiment impresionante este que tu parles pas Francais!
*c'est
English pls
oh vraiment! but the asker has asked the question in French LOL
aucune question n'était dans
uh huh, este que-tu parles japonais? ou chinois?
Je ne parlez pas francais bien! ^_^"
rather, un peu
OK but ypu speak English n
and I also don't know to speak in Japanese and Koreans languages

20N is the force acting on the body
please give the answer with full explanation , how??
first apply the fornula S=1/2 at² from there calculate a. then apply F= ma
got it?
yah

The question is a little vague to be honest.
I shall assume the body starts from rest.
And I am assuming you are asking about the net force on the body (which caused it to move, cuz there are gravity,normal)
now using second equation of motion
x= ut + 1/2 at^2
32= 0*4 +1/2 a 16
32=8 a
a=4 m/s^2
Now Net force = ma (newton's second law)
Force = 5 * 4 =20 N
There you go.
i hope its hlp you
