Question

When a mass m is attached to the spring of force constant k then the spring stretches by l. if the mass oscillates with amplitude l . what will be the maximum potential energy stored in the spring?

Answer 1

Hey there.....



Suppose there are 2 bodies of mass M1 and M2 sepreated by diatance "D".
Left in empty space.

( Note: Here empty space means Outer space)

And there's nothing around them within a radius of a quadrillion Lightyears.

Now these two bodies will attract each other (because of their gravitational forces). Such after some time they'll be touching each other.


Now what you have to do here is calculate that time taken by those two bodies to attract each other.
