Dr. John Paul Stapp was a U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, and was brought jarringly back to rest in only 1.40 s!Calculate the magnitude of his average acceleration during the first part of his motion. Express your answer in multiples of g by taking its ratio to 9.80 m/s2. calculate the magnitude his average deceleration during the second part of his motion. Express your answer in multiples of g by taking its ratio to 9.80 m/s2.
Very large accelerations can injure the body, especially if they last for a considerable length of time. One model used to gauge the likelihood of injury is the severity index ( SI ), defined as SI=a5/2t . In the expression, t is the duration of the accleration, but a is not equal to the acceleration. Rather, a is a dimensionless constant that equals the number of multiples of g that the acceleration is equal to. In one set of studies of rear-end collisions, a person's velocity increases by 16.6 km/h with an acceleration of 33.0 m/s2 . Let the +x direction point in the direction the car is traveling. What is the severity index for the collision?SI = ?How far d does the person travel during the collision if the car was initially moving forward at 5.20 km/h?d = ? m

A dolphin in an aquatic show jumps straight up out of thewater at a velocity of 13.0 m/s. (a) List the knowns in thisproblem. (b) How high does his body rise above the water?To solve this part, first note that the final velocity is now aknown and identify its value. Then identify the unknown, anddiscuss how you chose the appropriate equation to solve forit. After choosing the equation, show your steps in solving forthe unknown, checking units, and discuss whether the answeris reasonable. (c) How long is the dolphin in the air? Neglectany effects due to his size or orientation
