Two blocks of mass m and M are connected using a spring of spring spring constant k.(friction is absent everywhere). A force F is applied on M ,so that m just starts moving.What is the minimum magnitude of F? How will be the motion of system after the block of mass m start moving? would it be an accelerated motion of constant acceleration,a=F/(m+M) ?

Question

anonymous · Answer

Any force greater than zero will cause m to move, the motion of the system will be an acceleration motion of constant acceleration
