Q5. 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 magnitude vaA = 4 m/s. Determine the velocity magnitude vB of the particle as it passes position B. Hint: (1) Resolve the velocity into components parallel and perpendicular to the spring (say using polar coordinates), and the perpendicular component is the one that decides the angular momentum. (2) The system will obey both angular momentum conservation about O and energy conservation. 350 mm ww 54° VA -4 m/s B 65° 230 mm UB

Transcribed Image Text:Q5. 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 magnitude va = 4 m/s.
Determine the velocity magnitude Vß of the particle as it passes position B.
Hint: (1) Resolve the velocity into components parallel and perpendicular to the spring (say using
polar coordinates), and the perpendicular component is the one that decides the angular
momentum. (2) The system will obey both angular momentum conservation about O and energy
conservation.
