An archer shoots a 100 g arrow straight up in the air. The bow was drawn back 50 centimeter by a 150 Newton force. Find how high does the arrow rise assuming friction is negligible? Find how high does the arrow rise suppose the force of air friction on the arrow averages 0.080 Newton during the upward flight. Suppose the bow acts like an ideal spring.
