4. A young girl gives her toboggan a push of 4.0 m/s up a hill. It slides up the hill slowing
down at an acceleration of 8.0 m/s- [down). It comes to a stop and then slides back towards
her speeding up at the same rate as it slowed down on the way up. If the girl has to run 48 m
down the hill from where it first was pushed to get to where her sled stopped, find the
elapsed time for the journey.
