Question

A 0.01 kg block collides with horizontal massless spring of force constant k equal to 2 and by ap the spring gets compressed by 0.4 m if the coefficient of kinetic friction between the block and surface is 0.5 the speed of block at the time of collision is

Answer 1

Hola ^^" !

Edit : Can you please ignore that Instantaneous Velocity Part !

We have the speed at the time of collision as :
$7.75m {s}^{ - 1}$

Answer 2

Answer:

v = 6m/s (energy conservation)
