A particle is in linear S.H.M. between two points, A and B, 10 cm apart Take the direction from A to B as the positive direction and give the signs of
velocity, acceleration and force on the particle when it is:
(a) at the end A,
(b) at the end B,
© at the mid point of AB going towards A,
(d) at 2 cm away from B going towards A,
(e) at 3 cm away from A going towards B, and
(f) at 4 cm away from A going towards A.

(a) End A : Velocity = 0; acceleration +ve, force +ve. . .
(b) End B: Velocity = 0; acceleration - ve; force - ve.
© Velocity - ve; acceleration = 0, force = 0
[mean position].
(d) Velocity - ve; accelration = - ve; force - ve.
(e) Velocity + ve; acceleration + ve; force + ve
(f) Velocity - ve; acceleration + ve; force + ve
