For 14, an object moving in a straight line has velocity v(t) in the given time
Chapter 10, Problem 2(choose chapter or problem)
For 14, an object moving in a straight line has velocity v(t) in the given time interval. a. Find the time subintervals in which the velocity is positive and those in which it is negative. b. Find the distance the object travels in each of these subintervals. c. Use a single integral to find the displacement in the given time interval, and use a single integral to find the distance traveled in this interval. d. Show how you can find the answers to part c from the answers to parts a and b. e. Find the acceleration of the object at the midpoint of the time interval. v(t) = tan 0.2t cm/s, from t = 10 s to t = 20 s
