Problem 1 to 6: You are driving your brand new Mustang on a straight highway. Suddenly you felt a strong desire to check physics while driving and so you checked the gauge: It indicates that the speed is 80 kilometers per hour. You enjoyed driving for another hour while checking speeds. At the end of speeding up period of one hour, you read your car's speed as 160 kilometer per hour. Then suddenly you saw red and blue flashing light...

1. An airplane if flying horizontally at a constant height of 6 km above a fixed observation point. At a certain moment the angle of elevation θ is 30° and decreasing and the speed of the plane is 4 km/h. (a) How fast is 0 decreasing at this moment? (b) How fast is the distance between the plane and the observation point is changing at this moment? 2. Trajectory of a particle is described by parametrical equations as t,y P,...
