## Homework Statement

A projectile is shot at a hill, the base of which is 320 m away. The projectile is shot at 60° above the horizontal with an initial speed of 79 m/s. The hill can be approximated by a plane sloped at 19° to the horizontal. The equation of the straight line forming the hill is

y = x tan(19°) − 110.

Where on the hill does the projectile land? (Answer is supposed to be in the form

*x*,

*y*.)

## Homework Equations

y = x tan(19°) − 110.

## The Attempt at a Solution

Write expressions for the x and y coordinates of the projectile as a function of time.

x = 79 cos(60°) t
