2. (20 pts) Consider a spring-mass-damper system with equation of motion given by: $2\ddot{x} + 12\dot{x} + 116x = 0$ a) Is the system overdamped, underdamped or critically damped? Does the system oscillate? If the system oscillates then: b) Compute the frequency of the oscillations in rad/s and Hz. c) Compute the solution if the system is given initial conditions $x_0 = -1$ mm and $v_0 = -7$ mm/s

Ein - Eout = ?E system (m_eflow)in = (m_eflow)out + Qloss 9.) (20 points) A compressor is being used to pressurize air steadily from 100 kPa and 15°C to 650 kPa and 125°C. The mass flow rate of the air is 0.05 kg/s and heat losses per unit mass are 15.3 kJ/kg. Determine the shaft power input (kW) required to run this compressor. Neglect kinetic and potential energy changes. Note: $C_{pair} = 1.02 \frac{kJ}{kg \cdot K}$
