Question

An impulse of I = 30 N − sec is given at t = 0 to 3 kg block attached with 2 block with the spring in natural length. Initially the system is at rest and all surfaces are smooth. Find velocity of centre of mass in m / s at t = 5 sec ?

TestHub · Accepted Answer

I = Δ P ​ 30 = 3 ( v f ​ − 0 ) ⇒ v f ​ = 10 m / s ​ ⇒ v c m ​ = 5 3 × 10 + 2 × 0 ​ = 6 m / s ​ Velocity of centre of mass remains constant because there is no external force on the system. \end{document}
