Work Energy And Power Question 313

Question: A block of mass m moving with a velocity v0 on a smooth horizontal floor collides with a light spring of stiffhess k that is rigidly fixed horizontally with a vertical wall. If the maximum force imparted by the spring on the block is F, then

Options:

A) Fm

B) Fk

C) Fv0

D) None of these

Show Answer

Answer:

Correct Answer: D

Solution:

[d] Energy conservation between the positions A and B requires that ΛPE+KE=0 or

12kx212mv02=0

x=mkv0

Fmax=kx=mkv0

or Fmaxkmv0
