A block with mass m =6.5 kg is hung from a vertical spring. Whenthe mass hangs in equilibrium, the spring stretches x = 0.22 m.While at this equilibrium position, the mass is then given aninitial push downward at v = 4.1 m/s. The block oscillates on thespring without friction. 1) What is the spring constant of thespring? N/m 2) What is the oscillation frequency? Hz 3) After t =0.39 s what is the speed of the block? m/s 4) What is the magnitudeof the maximum acceleration of the block? m/s2 5) At t = 0.39 swhat is the magnitude of the net force on the block? N 6) Where isthe potential energy of the system the greatest? At the highestpoint of the oscillation. At the new equilibrium position of theoscillation. At the lowest point of the oscillation.
