...acceleration. At some later....? A sled starts from rest at the top of a hill and slides down with a constant acceleration. At some later....?
...time it is 14.4 m from the top; 2.00 s after that it is 25.6 m from the top, 2.00 s later 40.0 m from the top, and 2.00 s later it is 57.6 from the top. a) What is the magnitude of the average velocity of the sled during each of the 2.00-s intervals after passing the 14.4-m point? b)What is the acceleration of the sled? c) What is the speed of the sled when it passes the 14.4-m point? d) How much time did it take to go from the top to the 14.4-m point? e) How far did the sled go during the first second after passing the 14.4-m point?
