Statement-1 : Velocity and acceleration of a particle are given as :

= î – ĵ and = 2î + 2ĵ

This is a two dimensional motion with constant acceleration.

Statement-2 : Velocity and acceleration are two constant vectors.

= î – ĵ and = 2î + 2ĵ

This is a two dimensional motion with constant acceleration.

Statement-2 : Velocity and acceleration are two constant vectors.
