A 100 g block is connected to a horizontal massless spring of force constant 25.6 N/m. As shown in figure (a ), the block is free to oscillate on a horizontal frictionless surface. The block is displaced 3 cm from the equilibrium position and, at t = 0, it is released from rest at x= 0 . It executes simple harmonic motion with the positive x-direction indicated in figure ( a).
The position-time(x-t) graph of motion of the block is as shown in figure (b ).
\[\text { (a) }\]
When the block is at position A on the graph, its
- position and velocity both are negative
- position is positive, and velocity is negative
- position is negative, and velocity is positive
- position and velocity both the positive
Answer
(B) position is positive, and velocity is negative
