A child's slide has a vertical height of 1.7 m as shown. Two slides, X and Y , have the same height. Slide X is longer than slide Y , as shown. A child moves from rest down slide X and reaches a maximum speed $$\(v_{\mathrm{x}}\)$$. A second child moves from rest down slide Y and reaches a maximum speed $$\(v_{\mathrm{Y}}\)$$. The child on slide Y has a greater mass than the child on slide X . The resistive forces acting on both children can be ignored. Explain how $$\(v_{\mathrm{X}}\)$$ compares with $$\(v_{\mathrm{Y}}\)$$.
