A62.4 g mass is attached to a horizontal spring with a spring constant of 17.3 n/m and released from rest with an amplitude of 23.7 cm. what is the speed of the mass when it is halfway to the equilibrium position if the surface is frictionless? answer in units of m/s.

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m.the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.
