DISTANCE,DISPACEMENT

Statement-I : A particle is moving along x-axis. The resultant force F acting on it is given by F =- ax - b , wher a and b are both positive constants. The motion of this particle is not S.H.M. Statement-II : In S.H.M. resultant force must be proportional to the dispacement form mean position.

The dispacement of a body is given by 4s=M +2Nt^(4) , where M and N are constants. The velocity of the body at any instant is .

The dispacement of a body is given by 4s=M +2Nt^(4) , where M and N are constants. The velocity of the body at the end of 1 s from the start is .

The C-C distance in ethane is

Show that for a particle executing SHM, velocity and dispacement have a phase difference of pi//2 .

For a particle executing SHM, if x, v, a and F represent dispacement, velocity, acceleration and restoring force, then (A) vec(F).vec(x) is always negative (B) vec(v).vec(x) is always negative (C) vec(v) xx vec(a) is always zero (D) vec(a) xx vec(v) is always positive
