Question

Both the springs shown in figure (5−E2) are unstretched. If the block is displaced by a distance xand released, what will be the initial acceleration

Answer 1

Answer:

Explanation:

Let the block m be displaced towards left by displacement x

∴ F1 = –k1x   (compressed)

F2 = –k2x   (expanded)

ma=F1+F2

⇒a= -x(k1+k2)/m.

∴k1+k2 x/m opposite the displacement or towards the mean position.
