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.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy.work depends on the square of the change in potential energy.work is equal to the negative of the change in kinetic energy.work is equal to the square of the change in kinetic energy
