This Science News article and
National Geographic article (with an interesting video of cheetahs) covers research done by putting collars with GPS on several wild cheetahs as they engaged in hunts. They were able to measure the top speed, acceleration (and deceleration) as well as their movements as they hunted their prey. They were able to decelerate from 36 mph to 9 mph in three strides so they can change direction easily. The scientists first tested their
system on dogs on a beach so they could compare their GPS with the locations of the paw prints left in the sand
