Question
A particle is in linear simple harmonic motion between two extreme point A and B, 10 cm apart (see fig)
If the direction from A to B is taken as positive direction, what are signs of displacement x, velocity V and acceleration a, when the particle is at A?
If the direction from A to B is taken as positive direction, what are signs of displacement x, velocity V and acceleration a, when the particle is at A?
Answer: Option D
:
D
Displacement x = − 5 cm, i.e., x = − ve. Velocity at extreme points is zero. Acceleration is opposite to displacement. The a = +ve.
Hence the correct choice is (d)
