1. Black vultures excel at gliding flight; they can move long distances through the air without flapping their wings while undergoing only a modest drop in height. A vulture in a typical glide in still air moves along a path tipped 3.5 degrees below the horizontal. If the vulture moves a horizontal distance of 100 m, how much height does it lose?
2. In a typical greyhound race, a dog accelerates to a speed of 20m/s over a distance of 30m. It then maintains this speed. What would be a greyhound's time in the 100m dash? Assume constant acceleration for the first period.
3. The Nardo ring is a circular test track for cars. It has a circumference of 12.5km. Cars travel around the track at a constant speed of 100km/h. A car starts at the easternmost point of the ring and drives for 15 minutes at this speed.
(a)What distance, in km, does the car travel?
(b)What is the magnitude of the car's displacement, in km, from its initial position?
(c)What is the speed of the car in m/s?
