1kkk ya i got d thing tx yaar
if a particle of mass 2 g is located at origin and the force varies as the given relation
F(x)=9x4/5+ b x
Find the value of b after time t = 32 sec
...(IT IS MY OWN Q... if there is any mistake pls forgive me)

1Hint:no calculus required.....:) it will take less than 5 sec think again read the question again..
1hey yaar if the object is initially at rest then it will not move......
1i m also not convinced i mean if der is no force on particle at t=o bt der is sum force just after t=0 sec so yy particle ll remain it is?
11i don't agree with ur logic[2]
let the seniors or the admistrators have a look at this 1[1]
1At origin x =0 , there fore no force is experienced at origin itself... therefore no motion.... even after 32 sec it will remain at origin itself....therefore b can take any real value ==> -infinity to + infinity
11i am just having a 2nd order equation which i don't know how to solve
if u have a method please post
11use F=ma
2 X 10-3 a=9x4/5+bx
now u know that a = d2x/dt2
use it
solve the differential equation to get ur answer
