When she has reached her highest point

Reference no: EM13649096

A skier approaches the base of an icy, frictionless hill with aspeed of 13.9 m/s. The hill slopes upwardat18.0^\circ above the horizontal. Find the acceleration of this skier:

when she is going up the hill,
when she has reached her highest point,
and after she has started sliding down the hill.
