Homework Statement
A dart is thrown horizontally toward the bull's-eye, point P on the dart board in the figure, with an initial speed of 8.9 m/s. It hits at point Q on the rim, vertically below P 0.20 s later.
a) What is the distance PQ?
b) how far away from the dart board did the dart thrower stand?
Homework Equations
x=xi + .5(vi+vf)t
vf^2= vi^2 + 2a(xf-xi)
The Attempt at a Solution
I am not really sure how to begin this problem. I know the knowns are
vi = 8.9 m/s
t= 0.20 s
vf = 0 m/s
And I believe I need to use one of the kinematic equations.
