Problem 17PE
Professional Application Dr. John Paul Stapp was 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 his (a) acceleration and (b) deceleration. Express each in multiples of g (9.80 m/s2 ) by taking its ratio to the acceleration of gravity.

ANSWER:
Problem 17PE
Solution 17 PE
Step 1 of 3:
In this question , we need to find the acceleration and deceleration of Stapp rode rocket, and we
need to express the acceleration in terms of gravitational constant
Data given
Initial velocity
Final velocity
Time taken
Time to decelerate
