A particle moves in XY plane according to the relations

x=k t

and

y=k t(1-p t)

where

k

and

p

are positive constants and

t

is time. Therefore,

Options

Athe trajectory of the particle is a parabola.
Bthe particle has a constant velocity along X axis.
Cthe force acting on the particle remains in the same direction even if both $k$ and $p$ are negative constants.
Dthe particle has a constant acceleration along -Y axis.

Correct answer

D. the particle has a constant acceleration along -Y axis.
