Unformatted text preview: 11) Block 1 and block 2 have the same mass, m, and are released from the top of two inclined planes 11) C of the same height making 30° and 60° angles with the horizontal direction, respectively. If the coefficient of friction is the same ' cases, which of the blocks is going faster when it reaches the bottom of its respective incline? A) We must know the actual masses of the blocks to answer. B) Both blocks have the same speed at the bottom. D) Block 1 is as er. E) There is not enough information to answer the question.

### 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.
