Give example of a motion where ` x gt 0, vlt 0, agt ` at a particular instant.

Explanation

As per given condition, the motion can be represented by ` x (t) = A + B e^(-gamma t)
wher ` A gt Bamd `gamma gt0` positive constant.
Now , velocity, `v(t) =- B gammeae^(gamma t)`
Acceleration, ` a(t) = B gamma^(2) e^(gamma t)`
Therefore, for thsi motion ` x gt 0, v lt 0 and a gt 0` at a particular instant of time.
