A particle prjected from origin moves in x-y plane with a velocity (vect.) v = 3i + 6xj where i and j are the unit vectors along x and y axix respectively. Find the equation of the path...
Dear Sunrit The path equation is y = x 2 S x = x = ∫v x .dt = 3∫dt = 3t S y = y = ∫v y .dt = ∫6x dt = ∫6(3t) dt = ∫18tdt = 9t 2 Thus y = x 2
