A Hot Wheels car rolls off a table with a horizontal speed of 2.32 m/s and hits the floor a distance of 0.766 m from the table's edge. Determine the height (in cm) of the table. (Note: acceleration = -9.81 m/s/s)

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
