At any time t , a particle has a position vector (t^2+1)i+(3t-2)j , relative to the origin O . Show that the acceleration is always directed horizontally . Hence , find the angle between the velocity and acceleration of the particle at any time , t .
v=2ti+3j , a=2i
Since a=2i , the particle is always accelerating along the x-axis .
so am i correct ?
