4. (20 points)
A ski jumper starts with a horizontal take-off velocity of vo =20.0 m/s and lands on a hill inclined at 30.0o (see the Figure).Note: a convenient coordinate system may not be horizontal andvertical.
a) Determine the time (in seconds) between take-off and landing. (8pts.)
b) Determine the distance down the hill, d, of the jump. (6pts.)
c) What is the component of the ski jumperâs velocity along theinclined landing hill when he lands? (6 pts.)
