1.	A particle is in linear simple harmonic motion 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 at the end A.
Answer» Solution :In the figure, the point A and B, 10 cm apart, are the the extreme positions of theparticle in SHM, and the point O is the MEAN position. The direction from A to B is POSITIVE, as indicated. The direction of velocity, displacement and acceleration from A to B is positive. At the ene A (at extreme positive), velocity is zero, acceleration and force are DIRECTED TOWARDS B and are positive (0, +, +).
