4 The position of a particle in the xyplane at time t is r[t) = (Let) H [gem] j. Find an equation in x and v whose graph is the path of the particle. Then nd the particle's velocity and acceleration vectors att= In 3. The equation for the path of the particle is v : |:|. The velocity.r vector att= ln3 is v:(| I) i +( )j. [Simplify your answers.) The acceleration vector att= In 3 is a = {D} i + (D) j. [Simplify your answers.)
