Answer to Question #45811 in Mechanics | Relativity for ishani

Question

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.

Answer 1

All statements are wrong: if acceleration of a particle is constant (not a zero), its velocity cannot be the constant
vector.
