The average speed of a vehicle on a stretch of Route 134 between 6 A.M. and 10 A.M. on a typical weekday is approximated by the function f(t) = 13t − 26 t + 36 (0 ≤ t ≤ 4) where f (t) is measured in miles per hour, and t is measured in hours, with t = 0 corresponding to 6 A.M. At what time of the morning commute is the traffic moving at the slowest rate? A.M. What is the average speed of a vehicle at that time? mph

rate 1. True or False? Explain: a. If a car's speedometer is constant, then the car cannot be accelerating. b. Ifan =0 for a moving object, then the object cannot be accelerating. c. The arc length of a space curve depends on the parameterization. d. The curvature of a circle is the same as its radius. e. The normal component of acceleration is a function of both speed and curvature. 2. Projectile Motion: A projectile is launched with an initial...
