A1. A particle is located at the origin. A second particle is a distance D away in a direction [E A N]. At the same time, the first and second particles suddenly move at constant speeds |v1| and |v2| in directions [E Θ1 N] and [W Θ2 N] respectively. If D = 25m, A = 30o, Θ1 = 50o and Θ2 = 35o and |v1| = 5.3m/s, what is |v2|, and at what time do they meet? [5 points]

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.
