Participation exercise y = x2 j i. 2d curvilinear kinematics summary & review: position r(t) = x(t)i + y(t)j. = r(t)er path? v(t ) p r(t) a(t ) O: velocity, acceleration v(t) = r (t) = x i + y j a(t) = v (t) = r (t) = x i + y j. = s: 2 et + en = v et + v2 en, 2. Constrained: path geometry is de ned yielding a relationship between a single particle"s coordinates: One particle/point in two-dimensions (2d: 2 degrees of freedom (dof) for pos. , vel. (x, y) (x, y) (x, y) (r, ) (r, ) 2*n: path geometry is de ned yielding a relationship between a single particle"s coordinates: x=f(y) or y=f(x), r=f( ) or =f(r) etc. xa.
