(here, x is the displacement of the block and v is the velocity of the block, k is spring constant and b is damping constant.)
(here, x is the displacement of the block and v is the velocity of the block, k is spring constant and b is damping constant.)
- kx – bv
- –kx – bv
- –kx + bv
- None of these
Answer
