Unformatted text preview: Find (decide, then left click) : Given (decide, then left click) : a(t=0 → t 1 ), a(t 1 →t 2 ), v(0) = 0, v(t 1 )=400 m/s, and v(t 2 ) = 100 m/s s (t=0 → t 2 ) Kinematics-Rectilinear Motion Rocket Sled Example 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 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? Solve Is this your final answer? From previous problem, we have: Nope- add them...
