A typical sneeze expels material at a maximum speed of 58.6 m/s. Suppose the material begins inside the nose at rest, 2.00 cm from the nostrils. It has a constant acceleration for the first 0.250 cm and then moves at constant velocity for the remainder of the distance.
What is the acceleration as the material moves the first 0.250 cm (0.250 m)?
A sports car, starting form rest, can reach 0.40 km in 9.0 s. What is the magnitude of the constant acceleration required to do this?
Cheetahs have the highest top speed of any land animal, but they usually fail in their attempts to catch their prey because their endurance is limited. They can maintain their maximum speed of 30 m/s for only about 15 s before they need to stop.Thomson’s gazelles, their preferred prey, have a lower top speed than cheetahs, but they can maintain this speed for a few minutes. When a cheetah goes after a gazelle, success or failure is a simple matter of kinematics: Is the cheetah’s high speed enough to allow it to reach its prey before the cheetah runs out of steam?The following problem uses realistic data for such a chase.A cheetah has spotted a gazelle. The cheetah leaps into action, reaching its top speed of 30 m/s in a few seconds. At this instant, the gazelle, 160 m from the running cheetah, notices the danger and heads directly away. The gazelle accelerates at 4.5 m/s2 for 6.0 s, then continues running at a constant speed. After reaching its maximum speed, the cheetah can continue…

- Captain John Stapp is often referred to as the "fastest man on Earth." In the late 1940s and early 1950s, Stapp ran the U.S. Air Force's Aero Med lab, pioneering research into the accelerations which humans could tolerate and the types of physiological effects which would result. Manning the rocket sled on the famed Gee Whiz track, Stapp tested acceleration and deceleration rates in both the forward-sitting and backward-sitting positions. He would accelerate to aircraft speeds along the 1200-foot track and abruptly decelerate under the influence of a hydraulic braking system. On one of his most intense runs, his sled decelerated from 274 m/s (614 mi/hr) to a stop at -202 m/s/s. Determine the.... a. ... stopping distance. Distance b... stopping time.

A horse can maintain a top speed of 20 m/s for a long distance but has a maximum acceleration of only 6.0 m/s2, half what a good human sprinter can achieve with a block to push against. Greyhounds, dogs especially bred for feats of running, have a top speed of 17 m/s, but their acceleration is much greater than that of the horse.
