Additional problem: a simple pendulum, consisting of a string (of negligible mass) of length l with a small mass m at the end, is initially held horizontal (θ = 90o) and then released. (a) what is the maximum velocity that the mass attains after release? (b) at what angle, θm, is the power delivered to the ball by gravity a maximum as the pendulum swings down? take θ = 0 when the pendulum is vertical.

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.
