Chapter 12, Problem 48FP

At the instant shown, object A's speed is VA = 5.9 m/s, and it is increasing at 0.5 m/s²; object B's speed vg = 1.0 m/s, and it is decreasing at 1.3 m/s². Determine the magnitude of the relative velocity of A with respect to B. Object Bis travelling along a circular path with radius of r = 12 m. The distance between A and B is d = 3.0 m, the angle is = 25°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. 0 VA d Your Answer: Answer VB units

At the instant shown, object A's speed is vA = 5.9 m/s, and it is increasing at 1.2 m/s2; object B's speed vg = 2.3 m/s, and it is decreasing at 0.7 m/s2. Determine the magnitude of the relative acceleration of A with respect to Bin m/s2. Object Bis travelling along a circular path with radius of r= 14 m. The distance between A and Bis d = 3.6 m, the angle is 0 = 28°. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. d VB VA Your Answer: Answer

Car A is accelerating in the direction of its motion at the rate of 1.2m /sec2. Car B is rounding a curve of 150m radius at a constant speed of 54km /hr. Determine the velocity and acceleration which car B appears to have to an observer in car A if car A has reached a speed of 72km /hr for the positions represented.
