A spring attached to a mass is storing 200J of elastic potential energy. If the gorse on the mass from the spring is 50N calculate both the spring constant and its displacement from equilibrium X. Me:
How do I solve for spring constant if I don't have k or X? using Hooke’s Law

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s

Aprisoner is forced to go into one of three rooms, but he can choose which room. the first room is ablaze with fire. the second one is rigged with explosives that will go off as soon as he enters. the third contains a pair of lions who haven't eaten in years. which room should he choose to survive?
