  • question_answer
    During the compression of the spring, the net work done on the block is

    A) Positive

    B) Negative

    C) Zero

    D) Cannot say

    Correct Answer: B

    Solution :

    [b] Just before the block collides with the spring, theblock has some kinetic energy. But finally its KE becomes zero. Hence, during compression, net work done on the block is negative.
