- System shown in the figure is released from rest with mass 2 kg in contact with ground. Pulley and spring are massless and the friction is absent everywhere. The speed of 5 kg block when 2 kg block leaves the contact with the ground is (force constant of spring k=40 Nm -1 and .g=10 ms -2) <img class=img-fluid question-image alt=image src=https://cdn.tardigrade.in/img/question/physics/eb65030b9ccd14cfd5fa930aaaead804-.png />
