A 1.4-kg block is supported as shown by a spring of constant k = 400 N/m which can act in tension or compression. The block is in its equilibrium position when it is struck from below by a hammer which imparts to the block an upward velocity of 2.5 m/s. Determine
(a) The time required for the block to move 60 mm upward,
(b) The corresponding velocity and acceleration of theblock.
A tank contains a two-phase liquid-vapor mixture of Refrigerant 22 at 10 bar. The mass of saturated liquid in the tank is 25 kg and the quality is 60%. Determine the volume of the tank, in m^3, and the fraction of the total volume occupied by saturat..
