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 his: a. acceleration in his direction of motion
b. acceleration opposite to his direction of motion.

Explanation:

Given

Rocket attain a velocity of in a time period of

It was brought jarringly back to rest in only

Acceleration is the change in velocity of the object over a period of time

(a) Acceleration in his direction of motion

(b) acceleration opposite to his direction of motion i.e. deceleration is
