Position of particle at time t' is x = 3t, y = 21.Locus of path of particle is(a) Parabolic, symetrical about x-axis.(b) Parabolic, symetrical about y-axis.(c) Hyperbolic.(d) Straight line.

Answer»

option(b) is correct Reason: we wil just eliminate t from both the equation . so,

x = 3t² , and y =2t => t = y/2

just put this back.in x we get x = 3(y/2)² or x =3/4(y²)

the equation is y² = 4x/3

it is an equation of parabola symmetry about x.
