An archer stands at rest on a frictionless frozen lake; his total mass including his bow and quiver of arrows is 60.00 kg. He then fires a 0.030kg arrow at 50.0 m/s at an angle of 30.0° above the horizontal. If it takes 650N of force to break the ice and the arrow leaves the bow in 10ms, what force does the archer exert on the ice?
