(110) An archer must exert a force of 375 N on the midpoint of the bowstring shown in Figure a, such that the string makes an angle of 0 = 35.0° with the vertical. (10 PTS.) (a) Is the midpoint in force equilibrium? (1 PT.) (b) Draw the free-body diagram of the midpoint. (3 PTS.) (c) Determine the magnitude of the tension in the bowstring. (3 PTS.) (d) If the applied force is replaced by a stretched spring as in Figure b and the spring is stretched 30.0 cm from its unstretched length, what is the spring constant? Show the full work of calculation. (3 PTS.) 0 0 www a
