Question

A spring block system is place on a sough
horizontal surface have coefficient of friction The spring is given an initial elongation and then the block is released
from rest. Find out the initial
constant
acceleration of the block.
and maximum speed​

Answer 1

Answer:

Solution :

a. From Newton's second law, we get <br>

<br> b. From work energy principle <br>

<br>

<br>

<br> c. Speed will be maximum where net force is zero <br>

<br>

(extension) <br> Now from work-energy principle, we have <br>

<br> Solving we get,
