can we aply kinematic equations in this case,,,,

as i think here..

t=kx^{2 ,}so.. x=root of t/k..

and so we cant apply as this is non-uniform

am i right

not that the motion is non uniform
its acceleration is also changing wrt 2 time so we cant apply

karthik2007

What do you want here? If you want the displacement, it will be the area under the curve. If you want the velocity at any instant, it will be the derivative of the function at that point

no!!
differentiate both the sides wrt t
dx/dt=a
and
a comes out to be = 1/k2x
since a depends upon x so acceleration is not uniform and thus this motion cant be used with kinmatic eqs..

rate if useful
