An ice sled powered by a rocket engine starts from rest on a large frozen lake and accelerates at 13 m/sz. After some more time 151, the rocket engine is shut down and the sled moves with constant velocity 1) for a time 152. If the total distance traveled by the sled is 10000 m and the total time is 50 5, determine the times t1 and t2. 751 | | U! 152 | l L0 Determine the velocity '0. m/s At the 10000-m mark the sled begins to accelerate at -7 m/sz. What is the final position of the sled when it comes to rest? m How long does it take to come to rest? 5
