Question 2 0/2 points Calculate the acceleration of a 9 kg mass at x-0.05 m, if the mass is attached to a spring with stiffness k = 66 N/m. Give the answer to 2 decimal places. Answer: -3.67 x (-0.4) m/sec^2 x (m/s^2) Question 3 0/2 points Calculate the oscillation frequency of a 1 kg mass attached to a spring with k 132 N/m and allowed to oscillate. Give the answer to 2 decimal place. Answer: 18.05 x (1.83) sec x (Hz) Question 4 2/2 points A certain pendulum on earth has a frequency of 1.5 Hz. What would be the period of that same pendulum on Mars? (Assume that the acceleration due to gravity of Mars is 3.71 m/s2 and 9.8 m/sec^2 on Earth). Give the answer to 1 decimal place. Answer: 1.08 ✔ sec✔ Question 5 Calculate the angular frequency of a 4 kg mass on a spring with spring constant 200 N/m². Answer: 11.11 x (7.1) HZ x (rad/sec) 0/2 points
