5. Two cars are traveling around a circular track as shown below. Answer the following questions. a. Use the drawing provided to clearly indicate the origin and direction of û, and ûn for each car. a. b. If both cars are traveling at the same speed, which car has a greater normal acceleration? Justify your response in words. C. If both cars travel at 50 mph, what is their velocity in ft/s? Show your work. Magnitude rounded to 3 sig. fig. Magnitude rounded to 3 sig. fig. Units 6. At the instant shown below, the bucket of the backhoe traces a path defined by r = 25 sin 0 ft, where 8 is in radians. When the bucket is at 0 = 100°, its angular velocity is 1.8 rad/s and its angular acceleration is Ö = -0.4 rad/s2. Answer the following questions. What is the radius, r, at this instant? Show your work. Magnitude rounded to 3 sig. fig. Units b. What is ve at this instant? Show your work. Units 7-400 ft = fe= 390 ft B
