Hello, I have a really short hw that I'd appreciate any help on. Thank you!

In-Class Assignment Simple Harmonic Motion #1 Name: Date: Class: AP Physics BOX IN YOUR FINAL ANSWER WITH CORRECT UNITS. Use g = 10 m/s* 1. M An object on a horizontal, frictionless surface is attached to a spring, displaced, and then released. If it is displaced 0.12m from its equilibrium position and released after 0.8s its displacement is found to be 0.12m on the opposites side, and passed the equilibrium position once during the interval. Find: A) Amplitude B) Period C) Frequency The figure shows a 2.4 kg ball attached to an x(cm) unknown spring and allowed to oscillate. Find the: A) Period [(s) B) Frequency C) Angular Frequency D) Amplitude E) Spring Constant 3. An object is undergoing SHM with a frequency of 4 Hz and amplitude 1.8 cm. How long does it take for the part to go from 0 to -1.8 cm? 4. A 0.4 kg object is undergoing SHM. It has an acceleration of 1.8 m/s? when it is at a position of 0.3m. What is the time for one oscillation? 5. A 0.5 kg mass on a spring has velocity as a function of time given by (1) = ~(3.60 cm/s) sin[(4.71 rad/s)t (m/2)] Find: A) Period B) Amplitude C) Maximum acceleration of the mass D) The force constant of the spring 6. A fisherman hangs a 65 kg fish from a spring with negligible mass. The fish stretches the spring 0.18m and is at rest. The fish is then pulled down 5cm and released. A) Find the spring constant of the spring. B) What is the period of oscillation of the fish? C) What is the maximum speed it will reach? 7. A 175-g glider on a frictionless track is attached to a spring with a spring constant pf 155 N/m. It is moving at 0.815 m/s and is 3cm from its equilibrium point. Use energy conservation to find: A) Amplitude B) Maximum Speed C) Angular Frequency
