A particle is in linear simple harmonic motion between two points, A and B, 10 \mathrm{~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 3 \mathrm{~cm} away from A going towards \mathrm{B}, and
(b) at 4 \mathbf{c m} away from B going towards A.

A particle is in linear simple harmonic motion between two points, A and B, 10 \mathrm{~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 3 \mathrm{~cm} away from A going towards \mathrm{B}, and
(b) at 4 \mathbf{c m} away from B going towards A.

(a) Positive, Positive, Positive

From the end A, the particle is travelling toward point 0. This motion is going from A to B, which is the standard positive direction. As a result, the velocity, acceleration, and force measurements are all positive.

(b) Negative, Negative, Negative

From the end A, the particle moves toward point 0. The motion is in the traditional positive direction, from A to B. As a result, velocity, acceleration, and force all have positive values.
