9. A spring with constant k= 78 N/m is at the base of a frictionless, 30.0°-inclined plane. 0.50-kg block is pressed against the spring, compressing it 0.20 m from its equilibrium position. The block is then released. If the block is not attached to the spring, how far up the incline will ittravel before it stops?A A) 0.080 mB) 0.16 mC) 0.32 mD) 0.64E) 1.1 m

10. A simple pendulum on earth has a period of 6.0 s. What is the approximate period of this pendulum on the moon where the acceleration due to gravity is roughly 1/6 that of earth?
11. An iron ball hangs from a 21.5-m steel cable and is used in the demolition of a building at a location where the acceleration due to gravity is 9.78 m/s2. The ball is swung outward from its equilibrium position for a distance of 4.20 m. Assuming the system behaves as a simple pendulum, find the maximum speed of the ball during its swing.

12. The maximum compressional stress that a bone can withstand is 1.6 × 108N/m2before it breaks. A thighbone (femur), which is the largest and longest bone in the human body, has a cross sectional area of 7.7 × 10–4m2. What is the maximum compressional force that can be applied to the thighbone?
