An archer stands at rest on frictionless ice; his total mass including his bow and quiver of arrows is 60.00 kg. (a) If the archer fires a 0.030 0-kg arrow horizontally at 50.0 m/s in the positive x - direction, what is his subsequent velocity across the ice? (b) He then fires a second identical arrow at the same speed relative to the ground but at an angle of 30.0° above the horizontal. Find his new speed. (c) Estimate the average normal force acting on the archer as the second arrow is accelerated by the bowstring. Assume a draw length of 0.800 m.
