CONCEPT QUIZ 1. If a particle moves in the x - y plane, its angular momentum vector is in the A) x direction. B) y direction. C) z direction. D) x - y direction. 2. If there are no external impulses acting on a particle A) only linear momentum is conserved. B) only angular momentum is conserved. C) both linear momentum and angular momentum are conserved. D) neither linear momentum nor angular momentum are conserved.
6/194. The phenomenon of vehicle tipping is investigated in this problem. The vehicle is sliding sideways with speed v 1 and no angular velocity when it strikes a small curb. Assume no rebound of the right-side tires and estimate the speed v 1 that will cause the vehicle to roll completely over to its right side. Mass is 2300 kg, I G is 900 kg m 2 . What v will make it tip? IC25.1 – SUV Roll Over Don’t Do this at Home

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
