Problem 3 An electric system is rated 15 kVA, 240 V at a 0.5 leading power factor: a) Determine the impedance of the system in rectangular form. b) Find the total resistance and the total reactance (inductive or capacitive) within the electric system. (Assume that all elements are in series.) c) Find the average power delivered to the system.

Asailboat is traveling to the right when a gust of wind causes the boat to accelerate leftward at 2.5m/s2 for 4s. after the wind stops, the sailboat is traveling to the left with a velocity of 3.0m/s.assuming the acceleration from the wind is constant, what was the initial velocity of the sailboat before the gust of wind? answer using a coordinate system where rightward is positive.
