A block of mass m1 is released from rest at a height h 1 above the level of the horizontal surface where another mass m 2 is resting as shown above. There is no 1 friction between the blocks and the surface they are sliding on and effects due to {a rotation of the objects may be ignored. a. Using conservation of energy, derive an expression that relates the height from which an object is released in the above conﬁguration to its velocity when it reaches the horizontal portion of the surface. (2 points) b. Write down an equation which reﬂects the conservation of linear momentum as it pertains to this scenario. (2 points) c. Write down and equation that reﬂects the conservation of energy in this scenario provided that a collision between the blocks is fully elastig (2 points) d.

### 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.
