Document Summary
Spring 2018 physics 7a lec 001 (yildiz) midterm i: (20 points) wild geese are known for their lack of manners. One goose is flying at a constant altitude hg when it sees a car in the distance moving towards itself. The goose is flying at a speed of vg and the car is moving at a speed of vc relative to the ground. The center of the windshield is hc off the ground: the goose decides to poop on the windshield of the car. At what horizontal separation d between the goose and the windshield does the goose need to take action: the driver sees what the goose is after and steps on the accelerator right when the goose is d away. [neglect the shape of the car and assume it is hc off the ground everywhere] 2. (20 points) a small cart is going up an inclined track with nothing pushing it, so it is decelerating.
