The position of a particle moving with constant acceleration is given by x(t) = 6t2 + 6t + 4 where x is in meters and t is in seconds.
(A) Calculate the average velocity of this particle between t = 6 seconds and t = 10 seconds.
(B) At what time during this interval is the average velocity equal to the instantaneous velocity?
(C) How does this time compare to the average time for this interval? (a) It is larger. (b)It is smaller. (c)They are the same.
The first controlled, sustained flight in a heavier-than-air craft was made by Orville Wright on December 17, 1903. The plane took off at the end of a rail that was 60 feet long, and landed 12 seconds later, 180 feet away from the beginning of the..
