One day an old lady was walking up a mountain and made it to a cliff with her grandbaby in a stroller. Her cousin was with her holding the baby, and the old lady bent down to tie her shoes which caused the empty stroller to roll down the hill and off a high eliff. Ignoring air resistance (see section 3.4 in the text), what is the horizontal component (that meansx-direction) of its acceleration? What is the vertical component (that means           y-direction) of its acceleration?
