Part A Two cars, both of mass m, collide and stick together. Prior to the collision, one car had been traveling north at speed 30, while the second was traveling at speed 21 at an angle @ south of east (as indicated in the figure). After the Find the speed Urinal of the joined cars after the collision. collision, the two-car system travels at speed Vfinal at an angle 0 east of north. (Figure 1) Express your answer in terms of " and @. > View Available Hint(5) Ufinal = vy3.25 - 3sing Submit Previous Answers Correct Part B What is the angle 0 with respect to north made by the velocity vector of the two cars after the collision? Express your answer in terms of @. Your answer should contain an inverse trigonometric function using the notation asin, atan etc. and not arcsin, arctan etc. > View Available Hint(5) AEd cos cp 0 = atan 2 - sin p Submit Previous Answers Request Answer X Incorrect; Try Again; 2 attempts remaining Figure Provide Feedback 2v final 3v +Z
