Question

Rocket-powered sleds are been used to test the
responses of humans to acceleration. Start-
ing from rest, one sled can reach a speed of
504 m/s in 1.84 s and can be brought to a stop
again in 2.28 s.
Find the acceleration of the sled while ac-
celerating.
Answer in units of m/s2

Answer 1

use vt = vo + a t
where vt is the final speed, vo is the initial speed, a is acceleration and t is time unit.,

Answer 2

This question does not have an answer, because the aceleration WHILE acelerating you need more info, what you can get is the average aceleration, doikng what the guy said on the previous post.

Answer 3

IOW, it is not undergoing uniform acceleration.
