A mass of 1 kg attached to a spring with a spring constant of 112 N/m oscillates horizontally on a smooth frictionless table with an amplitude of0.8 m.
(a) When the mass is 0.35 m away from equilibrium, determine its total mechanical energy.
(b) When the mass is 0.35 m away from equilibrium, determine the system's potential energy and the mass's kinetic energy, potential energy and kinetic energy.
(c) When the mass is 0.35 m away from equilibrium, determine the mass's kinetic energy when it is at the equilibrium point.
Determine the velocity of the airplane required for pilot to experience weightlessness at the top of the circular path.
At a section in a passage, the pressure is 150 kPa (abs), the temperature is 10 deg C, and the speed is 120 m/s. For isentropic flow of air, determine the Mach number at the point where the pressure is 50 kPa (abs). Sketch the passage shape.
