Question

With how much velocity a block of mass 2kg shouldmove on a friction less surface so as to compressa spring with force constant 2 newton/meter by4 meter

Answer 1

Since there are no non-conservative forces,

So using conservation of mechanical energy,

(1/2)mv^2 = (1/2)kx^2

Now on putting all the values in the above equation, you will get the maximum compression of the spring and that will be = 2.
