Question

9. In the following sketch, a spring is oscillating back and forth with negligible friction. Label with the corresponding letter the Maximum kinetic energy (A), the maximum force (B), the maximum spring potential energy (C), and maximum velocity (D). You can sketch the image below on your paper or print it out !x=0 beee I eeeeeeto ere fecreto 10. You decide to bungee jump from a tall bridge, 100 m tall. Your mass is 70 kg. The relaxed length of the bungee cord (k = 17 N/m) is 20 m. Would you hit the water below or safely jump? Justify your answer with data. 11. Abducted position is where the arm is lifted out in front of you with the elbow not bent. What is the torque about the shoulder if the arm is held in an abducted position at 60 degrees from the body in the frontal plane while holding a 10 kg dumbbell? Assume that the mass of the arm is 6 kg, its center of mass is located 38 cm from the shoulder joint center, and the arm's total length is 80 cm. Abducted position is where the arm is lifted out in front of you with the elbow not bent.
