How far down the slope does the arrow hit if it is shot with a speed of 50 m/s? hint: there are several strategies to solve this problem. this hint discusses two different methods. method 1: the arrow must land on the slope, so write y(x) of the slope as y= tan(phi)*x, where phi is angle of the slope and it must be negative. note that you need to define a coordinate system, which you might assign the origin at the position of the archer, and +x is to the right in graphic. all angles must be with respect to the positive x direction. the slope angle in the picture does not conform to this requirement so you have to determine the slope angle from the information given. that is why you should write -phi for the angle of the slope.
