he position of an object moving along an x axis is given by x = 3.27 t - 4.20 t2 + 1.02 t3, where x is in meters and t in seconds. Find the position of the object at the following values of t: (a) 1 s, (b) 2 s, (c) 3 s, and (d) 4 s. (e) What is the object's displacement between t = 0 and t = 4 s? (f) What is its average velocity from t = 2 s to t = 4 s?

A particle moves in one dimension, and its position as a function of time is given by x = (2.2 m/s)t + (−3.2 m/s2)t2. (a) What is the particle's average velocity (in m/s) from t = 0.45 s to t = 0.55 s? (Indicate the direction with the sign of your answer.) Average velocity is the change in position over change in time. Think about how to use the function to find the change in position. m/s (b) What is the particle's average velocity (in m/s) from t = 0.49 s to t = 0.51 s? (Indicate the direction with the sign of your answer.) m/s

Chapter 02, Problem 10 In reaching her destination, a backpacker walks with an average velocity of 1.26 m/s, due west. This average velocity results, because she hikes for 6.62 km with an average velocity of 2.54 m/s due west, turns around, and hikes with an average velocity of 0.381 m/s due east. How far east did she walk (in kilometers)? dw VE West East dɛ Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: Open Show Work
