Chapter 3.2, Problem 3.2TYU
A sled travels over the crest of a snow-covered hill. The sled slows down as it climbs up one side of the hill and gains speed as it descends on the other side. Which of the vectors (1 through 9) in the figure correctly shows the direction of the sled’s acceleration at the crest? (Choice 9 is that the acceleration is zero.)

The coordinates of a bee flying in the xy-plane are given by x(t) = At and y(t) = C - Bt², where
A = 3.2 m/s, B = 1.4 m/s², and C= 2.5 m. Calculate the velocity and acceleration vectors of the bee
as a function of time. Write your answers in unit vector notation.

vector?
A bike travels 6.53 x 103 m at 67.9 degrees North of East in a time of 2.56 x 103 seconds. The biker then has a drink for 1.23 x 103 seconds. She then rode a distance 6.05 x 103 m South in a time of 2.93 x 103 m seconds. She paused for 1.88 x 103 seconds, and it takes her back to her starting point. What was the magnitude of the average velocity of their entire ride?
