A rocket sled accelerates along a long, horizontal rail.
Chapter 2, Problem 2.30(choose chapter or problem)
A rocket sled accelerates along a long, horizontal rail. Starting from rest, two rockets burn for \(10 \text { s }\), providing a constant acceleration. One rocket then burns out, halving the acceleration, but the other burns for an additional \(5 \text { s }\) to boost the sled's speed to \(625 \text { m/s }\). How far has the sled traveled when the second rocket burns out?
