A particle starts moving from rest the origin `&` moves along positive `x-` direction . Its rate of change of kinetic energy with time shown on `y-` axis veries with time `t` as shown in the graph. If  position, velocity , acceleration `&` kinetic energy  of the particle at any time `t` are `x,v,a,& k` respectively then which of the option `(s)` may be correct ?
