System shown in figure is released from rest. Pulley and spring is massless, and friction is absent everywhere. The speed of 5 kg block when 2 kg block leaves the contact with ground is:
(Take force constant of spring k = 40 N/m and g = 10 m/s2)
(Take force constant of spring k = 40 N/m and g = 10 m/s2)
- \(\sqrt{2}\)m/s
- \(2 \sqrt{2} \mathrm{~m} / \mathrm{s}\)
- 2 m/s
- \(4 \sqrt{2} \mathrm{~m} / \mathrm{s}\)
Answer
(B) 2 2 ~m / s
