Question

Pls answer urgently required

The block shown in the figure is under equilibrium on smooth surface. Spring force and contact force
by ground on the block are​

Answer 1

Answer:

max spring force will be at

max compression and what will

be the instant when kinetic

energy is zero

as spring force is converative ,

ui+ KEi= uf+KEF, conservation of mechanical energy

so,

ui=2k(०)२=०,uf=२k×२

KEi=२mu२,KEf=२m(०)२=०

so,

२k×२=२mv२

X=kmv[ make compression]

so max spring force=kx =(km)v

Explanation:

hope it's helpful।
