Question

The displacement x of a particle varies with time according
to the relation x = a/b (1-e⁻ᵇᵗ). Then select the false
alternatives.
(a) At t = 1/b, the displacement of the particle is nearly
2/3 (a/b)
(b) the velocity and acceleration of the particle at t = 0 are
a and –ab respectively

x = a/b
(d) the particle will not come back to its starting point at
t → [infinity]
