PHYISCS

here is the question

Once you have completed Task#2, post two questions that is for elastic energy and simple harmonic motion in the forum with answer solutions.

Read THIS what you have to do is make me 2 similar questions as below and solve them step by step that's all

here is 2 questions with the answers :

1} A spring k=7.50 me has been stretched 0.40m from its equilibrium position. What is the potential energy now stored in the spring? W=112 le}"2 W=1/2(7.50mel(0.40m]\"2 W=O.6J 2lA mass is attached to a spring with a force constant of 45 Wm. The spring and mass are set into simple harmonic motion on a horizontal surface. The period of vibration of this mass is 0.555. K=45N/m T=O.55s M=? T = 271% 0. 55s : 211' Xm 0.55s 2 : F 2 27: 45N/m 7. 662x10'352 45N/m :M M:0.34kg
