Rocket Sled Example In Class 3.1 The sled starts from rest and accelerates at: a= -0.003 v 2 m/s 2 Until its velocity decreases to 100 m/s. a= 30 + 2t m/s 2 Until it reaches a velocity of 400 m/s. Then it hits a water brake and its acceleration is: What total distance did the sled travel? Solution: What general relationship will you use? What are your limits of integration? Since you will be integrating your velocity equation to determine position, it is important to keep your limits in general terms Set up your position equation How long until v= 400 m/s? What about the braking part? What approach? Set up your integral Solve Problem Type (decide):

Then it hits a water brake and its acceleration is: What is the sled’s total time of travel? What general relationship will you use? (decide, then hit space bar) What are your limits of integration?
