Question
Rocket-powered sleds are been used to test the
responses of humans to acceleration. Starting from rest, one sled can reach a speed of
424 m/s in 2.35 s and can be brought to a stop
again in 2.16 s.
Find the acceleration of the sled while accelerating.
Answer in units of m/s2

a1=(v2-v1)/t1=(424 - 0)/2.35 =180.43 m/s^2
a2=(v3-v2)/t2=(0-424)/2.16 =-196.3 m/s^2
a2=(v3-v2)/t2=(0-424)/2.16 =-196.3 m/s^2
