From the top of a hill located at a height of 2.4 m an arrow is fired with a speed of 32.8 m/s, and an inclination with respect to the horizontal of 27.6°. If on the base of the hill there is a stream whose width is 4.4 m, how far from the bank of the stream will the arrow fall?
Note: Approximate result with only one decimal place

A skier starts from rest at the top of a hill that is inclined at 9.8° with respect to the horizontal. The hillside is 240 m long, and the coefficient of friction between snow and skis is 0.0750. At the bottom of the hill, the snow is level and the coefficient of friction is unchanged. How far does the skier glide along the horizontal portion of the snow before coming to rest? m
