Motion in a Plane 217(Projectile Motion)19. A particle projected from origin moves in x-y planewith a velocity v 3i+6xj, where i and i arethe unit vectors along x and y axis. Find theequation of path followed by the particle

Answer»

The path equation is y = x^2

Sx= x = ∫vx.dt =3∫dt = 3t

Sy= y =∫vy.dt =∫6x dt =∫6(3t) dt =∫18tdt = 9t2

Thusy = x^2
