Question

Two blocks of masses m and m are moving with speed v1 and v2 in the same direction

Answer 1

Answer:

Two blocks of masses m and M are moving with speeds V1.

and V2 (V1 > V2) in the same direction on the frictionless. surface respectively, M being ahead of m.

An ideal spring of force constant k is attached to the backside of M (as shown).

Answer 2

Heya Mate.....

given mass of the block =m

given mass of the block =mand kinetic energy =

$= \frac{1}{2} {mv1}^{2}$

and it strikes the spring and moves a distance Xwhich is the compression of the spring  then kinetic energy is equal to the compression of the spring which is the spring potential energy

$\frac{1}{2}{ mv1}^{2} = \frac{1}{2} k {x}^{2}$

${x}^{2} = \frac{m}{ {k}^{v1} } ^{2}$

$x = v1 \sqrt{ \frac{m}{k} }$
