Question

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 

(a) at the end A, 

(b) at the end B, 

(c) 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 B going towards A.

Answer 1

	Velocity	Acceleration	Force on the particle
(a) at the end A	0	+	+
(b) at the end B	0	-	-
(c) at the mid point of AB going towards A	-	0	0
(d) at 2 cm away from B going towards A	-	-	-
(e) at 3 cm away from A going towards B	+	+	+
(f) at 4 cm away from B going towards A	-	-	-
