2p 1e A position-dependent force (x, y) = axy (with a a constant) acts on an object with mass m. The object is released from rest at position (xo, y1) (with y a nonzero constant). When the object is at position (x1, y) its speed is v. What was the original position to where the object was released from rest? a b d f g h x0 = x mv ayi xo = mv ay mv ay x0 = x0=0 X0 = X1 + m a y1 'm U1 - x xo x U1 xo = my a y 'm v1 x = x1 - m 1 mv ay X1
