An archer performs 20.0 J of work to stretch a bow, storing elastic potential energy in it (much like a spring). The archer then loads an arrow of mass 100 g into the stretched bow, and fires it at an angle of 30.0° above the horizontal. What is the horizontal component of the arrow’s velocity as it leaves the bow
A. 20.0 m/s
B. 0.63 m/s
C. 17.3 m/s
D. 10.0 m/s
E. 0.55 m/s
