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.

Explanation:

Given

Initial velocity(u)=0

Final Velocity(v)=282 m/s

time taken=5 s

acceleration to acquire 282 m/s

a=5.74g

(b)deceleration

It comes to rest in 1.4 s

initial velocity of Just before deceleration is 282 m/s

v=u+at

a in terms of g

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

that the claims meet official rules.

don't misinterpret the claims
