Chapter 3 Kinetics of Particles - Question 5 [In Persian]
A particle of mass 𝑚 moves with negligible friction on a horizontal surface and is connected to a light spring fastened at 𝑂. At position 𝐴 the particle has the velocity 𝑣𝐴 = 4 m/s. Determine the velocity 𝑣𝐵 of the particle as it passes position 𝐵. The stiffness of the spring is k=193.75𝑚.
